- when a view is deleted, it is removed from left menu + from list views
in dropdown
- deactivated fields are not suggested as options to group records by
for a view (only in FE, not forbidden by BE)
## Context
After flushing the Redis cache (e.g., via `cache:flush` command), users
get stuck in an infinite loop showing "Your workspace has been updated
with a new data model. Please refresh the page." - refreshing the page
doesn't help.
## Root Cause
When the cache is flushed, `getMetadataVersion()` returns `undefined`.
The version comparison in the error handler then becomes:
```typescript
requestMetadataVersion !== `${currentMetadataVersion}`
// Evaluates to: "5" !== "undefined" → always true
```
This triggers the schema mismatch error on every request, even after
page refresh.
## History
| Date | Commit | What Happened |
|------|--------|---------------|
| Aug 2024 | #6691 (`17a1760afd`) | Introduced the
`${currentMetadataVersion}` template literal that converts `undefined`
to the string `"undefined"` |
| Dec 2025 | #16536 (`0035fc1145`) | Removed the safety check that would
throw an early error when cache is empty, allowing `undefined` to
propagate |
## Fix
Add `isDefined(currentMetadataVersion)` check before comparing versions.
If the server doesn't have a cached version, we shouldn't treat it as a
mismatch - the schema factory already handles populating the cache when
it actually needs the version.
```typescript
if (
requestMetadataVersion &&
isDefined(currentMetadataVersion) && // ← Added this check
requestMetadataVersion !== `${currentMetadataVersion}`
) {
```
## Testing
1. Flush the cache: `npx nx run twenty-server:command cache:flush`
2. Refresh the page
3. Verify no infinite loop occurs and app loads normally
Closes [571](https://github.com/twentyhq/core-team-issues/issues/571).
Replicates the behavior of number field and allows specifying the number
of decimals for currency field.

Currencies around the world have a maximum of three decimal places -
BHD, KWD etc. However, I have added a maximum of five decimal places in
case someone wants to use the currency field type for displaying things
like `per-second-billing` or `exchange rates`.

## Summary
This PR ensures usage alerts are created for all billing scenarios.
## Background
Per [Stripe
documentation](https://docs.stripe.com/billing/subscriptions/usage-based/alerts),
usage alerts are **one-time per customer** - they trigger once and only
consider usage reported after the alert is created. This means we need
to create a new alert whenever:
1. ✅ Subscription is created (trial) - Already implemented
2. ✅ Trial ends (user becomes Active subscriber) - **Added in this PR**
3. ✅ Credit tier changes (upgrade) - **Added in this PR**
4. ✅ **New billing cycle starts** - **Critical fix in this PR!**
## The Issue
Previously, the invoice webhook reset `hasReachedCurrentPeriodCap =
false` at cycle end, but didn't create a new alert. This meant after the
first billing period, there was no alert to trigger and users could
exceed their limit without being blocked.
## Changes
### 1. Invoice Webhook (`billing-webhook-invoice.service.ts`)
When invoice is finalized for `subscription_cycle`:
- Reset `hasReachedCurrentPeriodCap = false` ✅ (already done)
- **NEW**: Create alert at the current tier cap
### 2. End Trial Period (`billing-subscription.service.ts`)
In `endTrialPeriod()`:
- **NEW**: Create alert at the paid tier cap (not trial cap)
### 3. Credit Tier Upgrades (`billing-subscription.service.ts`)
In `changeMeteredPrice()`, when upgrading immediately (not scheduled for
period end):
- **NEW**: Reset `hasReachedCurrentPeriodCap = false`
- **NEW**: Create alert at new tier cap
### 4. Alert Title Update (`stripe-billing-alert.service.ts`)
Changed from "Trial usage cap" to "Usage cap" since alerts are now used
for all scenarios.
## Stripe Alert Limits
- Max 25 alerts per meter+customer combination
- Alerts only evaluate usage reported after creation
- One-time alerts trigger once per customer
With monthly billing cycles + occasional tier changes, we should stay
well under the 25 alert limit.
## Testing
- TypeScript typechecking passes
- Backend services properly inject new dependencies
This PR presents an attempt to increase the speed of the tests to run,
by using the same front-end built for Front and E2E CIs. It implied
merging front and E2E in one CI, but allowed to still have two different
status, and to have E2E run even if no front files have changed.
Also now using depot to build FE.

/>
Fixed inconsistency where List view (Group By) still showed empty groups
while Kanban hides them.
Update `visibleRecordGroupIdsComponentFamilySelector` now filters out
groups with zero records using
`recordIndexRecordIdsByGroupComponentFamilyState` and
`recordIndexShouldHideEmptyRecordGroupsComponentState`, ensuring empty
groups are consistently hidden across views.
Fixes#16212
Fixes: #16734
Solution:
The ObjectOptionsDropdownDefaultView was reading from
recordIndexFieldDefinitionsState via useObjectOptionsForBoard, while
field visibility changes update currentRecordFieldsComponentState. This
caused the "X shown" count to remain stale after hiding fields.
Changed to use visibleRecordFieldsComponentSelector (same state source
used by ViewFieldsVisibleDropdownSection) so both components react to
the same state updates.

## Summary
This PR adds user-friendly error handling for AI chat features,
specifically for **billing credits exhausted** and **API key not
configured** errors.
## Changes
### Backend
- Added `BILLING_CREDITS_EXHAUSTED` exception code with 402 status
- Added `API_KEY_NOT_CONFIGURED` exception code with 503 status
- Added billing check before AI chat streaming in
`agent-chat.controller.ts`
- Added error code to HTTP exception response body for frontend error
type detection
- Created `AgentRestApiExceptionFilter` for agent-specific errors
### Frontend
- Created `AIChatBanner` - reusable banner component for error/warning
messages
- Created `AIChatCreditsExhaustedMessage` - shows upgrade prompts based
on user permissions
- Created `AIChatApiKeyNotConfiguredMessage` - shows configuration
guidance with docs link
- Created `AIChatErrorRenderer` - encapsulates error type switching
logic (fixes nested ternary)
- Created `AIChatStandaloneError` - displays errors when there are no
messages
- Split `aiChatErrorUtils.ts` into separate files (1 export per file):
- `AIChatErrorCode.ts`
- `extractErrorCode.ts`
- `isAIChatErrorOfType.ts`
- `isBillingCreditsExhaustedError.ts`
- `isApiKeyNotConfiguredError.ts`
- Added comprehensive test coverage (27 tests)
### Other
- Updated trial period banner messaging
## Testing
- All lint checks pass
- All 27 new tests pass
- TypeScript typecheck passes
Improvements :
- phase 2 date calculation issue
- quantity update issue
- unnecessary phase creation - schedule should be created only when a
next phase is planned
## Summary
This PR enforces the use of `@/` alias for imports instead of relative
parent imports (`../`).
## Changes
### ESLint Configuration
- Added `no-restricted-imports` pattern in `eslint.config.react.mjs` to
block `../*` imports with the message "Relative parent imports are not
allowed. Use @/ alias instead."
- Removed the non-working `import/no-relative-parent-imports` rule
(doesn't work properly in ESLint flat config)
### VS Code Settings
- Added `javascript.preferences.importModuleSpecifier: non-relative` to
`.vscode/settings.json` (TypeScript setting was already there)
### Code Fixes
- Fixed **941 relative parent imports** across **706 files** in
`packages/twenty-front`
- All `../` imports converted to use `@/` alias
## Why
- Consistent import style across the codebase
- Easier to move files without breaking imports
- Better IDE support for auto-imports
- Clearer understanding of where imports come from
Fixes https://github.com/twentyhq/twenty/issues/16110
This PR implements Temporal to replace the legacy Date object, in all
features that are time zone sensitive. (around 80% of the app)
Here we define a few utils to handle Temporal primitives and obtain an
easier DX for timezone manipulation, front end and back end.
This PR deactivates the usage of timezone from the graph configuration,
because for now it's always UTC and is not really relevant, let's handle
that later.
Workflows code and backend only code that don't take user input are
using UTC time zone, the affected utils have not been refactored yet
because this PR is big enough.
# New way of filtering on date intervals
As we'll progressively rollup Temporal everywhere in the codebase and
remove `Date` JS object everywhere possible, we'll use the way to filter
that is recommended by Temporal.
This way of filtering on date intervals involves half-open intervals,
and is the preferred way to avoid edge-cases with DST and smallest time
increment edge-case.
## Filtering endOfX with DST edge-cases
Some day-light save time shifts involve having no existing hour, or even
day on certain days, for example Samoa Islands have no 30th of December
2011 : https://www.timeanddate.com/news/time/samoa-dateline.html, it
jumps from 29th to 31st, so filtering on `< next period start` makes it
easier to let the date library handle the strict inferior comparison,
than filtering on `≤ end of period` and trying to compute manually the
end of the period.
For example for Samoa Islands, is end of day `2011-12-29T23:59:59.999`
or is it `2011-12-30T23:59:59.999` ? If you say I don't need to know and
compute it, because I want everything strictly before
`2011-12-29T00:00:00 + start of next day (according to the library which
knows those edge-cases)`, then you have a 100% deterministic way of
computing date intervals in any timezone, for any day of any year.
Of course the Samoa example is an extreme one, but more common ones
involve DST shifts of 1 hour, which are still problematic on certain
days of the year.
## Computing the exact _end of period_
Having an open interval filtering, with `[included - included]` instead
of half-open `[included - excluded)`, forces to compute the open end of
an interval, which often involves taking an arbitrary unit like minute,
second, microsecond or nanosecond, which will lead to edge-case of
unhandled values.
For example, let's say my code computes endOfDay by setting the time to
`23:59:59.999`, if another library, API, or anything else, ends up
giving me a date-time with another time precision `23:59:59.999999999`
(down to the nanosecond), then this date-time will be filtered out,
while it should not.
The good deterministic way to avoid 100% of those complex bugs is to
create a half-open filter :
`≥ start of period` to `< start of next period`
For example :
`≥ 2025-01-01T00:00:00` to `< 2025-01-02T00:00:00` instead of `≥
2025-01-01T00:00:00` to `≤ 2025-01-01T23:59:59.999`
Because, `2025-01-01T00:00:00` = `2025-01-01T00:00:00.000` =
`2025-01-01T00:00:00.000000` = `2025-01-01T00:00:00.000000000` => no
risk of error in computing start of period
But `2025-01-01T23:59:59` ≠ `2025-01-01T23:59:59.999` ≠
`2025-01-01T23:59:59.999999` ≠ `2025-01-01T23:59:59.999999999` =>
existing risk of error in computing end of period
This is why an half-open interval has no risk of error in computing a
date-time interval filter.
Here is a link to this debate :
https://github.com/tc39/proposal-temporal/issues/2568
> For this reason, we recommend not calculating the exact nanosecond at
the end of the day if it's not absolutely necessary. For example, if
it's needed for <= comparisons, we recommend just changing the
comparison code. So instead of <= zdtEndOfDay your code could be <
zdtStartOfNextDay which is easier to calculate and not subject to the
issue of not knowing which unit is the right one.
>
> [Justin Grant](https://github.com/justingrant), top contributor of
Temporal
## Application to our codebase
Applying this half-open filtering paradigm to our codebase means we
would have to rename `IS_AFTER` to `IS_AFTER_OR_EQUAL` and to keep
`IS_BEFORE` (or even `IS_STRICTLY_BEFORE`) to make this half-open
interval self-explanatory everywhere in the codebase, this will avoid
any confusion.
See the relevant issue :
https://github.com/twentyhq/core-team-issues/issues/2010
In the mean time, we'll keep this operand and add this semantic in the
naming everywhere possible.
## Example with a different user timezone
Example on a graph grouped by week in timezone Pacific/Samoa, on a
computer running on Europe/Paris :
<img width="342" height="511" alt="image"
src="https://github.com/user-attachments/assets/9e7d5121-ecc4-4233-835b-f59293fbd8c8"
/>
Then the associated data in the table view, with our **half-open
date-time filter** :
<img width="804" height="262" alt="image"
src="https://github.com/user-attachments/assets/28efe1d7-d2fc-4aec-b521-bada7f980447"
/>
And the associated SQL query result to see how DATE_TRUNC in Postgres
applies its internal start of week logic :
<img width="709" height="220" alt="image"
src="https://github.com/user-attachments/assets/4d0542e1-eaae-4b4b-afa9-5005f48ffdca"
/>
The associated SQL query without parameters to test in your SQL client :
```SQL
SELECT "opportunity"."closeDate" as "close_date", TO_CHAR(DATE_TRUNC('week', "opportunity"."closeDate", 'Pacific/Samoa') AT TIME ZONE 'Pacific/Samoa', 'YYYY-MM-DD') AS "DATE_TRUNC by week start in timezone Pacific/Samoa", "opportunity"."name" FROM "workspace_1wgvd1injqtife6y4rvfbu3h5"."opportunity" "opportunity" ORDER BY "opportunity"."closeDate" ASC NULLS LAST
```
# Date picker simplification (not in this PR)
Our DatePicker component, which is wrapping `react-datepicker` library
component, is now exposing plain dates as string instead of Date object.
The Date object is still used internally to manage the library
component, but since the date picker calendar is only manipulating plain
dates, there is no need to add timezone management to it, and no need to
expose a handleChange with Date object.
The timezone management relies on date time inputs now.
The modification has been made in a previous PR :
https://github.com/twentyhq/twenty/issues/15377 but it's good to
reference it here.
# Calendar feature refactor
Calendar feature has been refactored to rely on Temporal.PlainDate as
much as possible, while leaving some date-fns utils to avoid re-coding
them.
Since the trick is to use utils to convert back and from Date object in
exec env reliably, we can do it everywhere we need to interface legacy
Date object utils and Temporal related code.
## TimeZone is now shown on Calendar :
<img width="894" height="958" alt="image"
src="https://github.com/user-attachments/assets/231f8107-fad6-4786-b532-456692c20f1d"
/>
## Month picker has been refactored
<img width="503" height="266" alt="image"
src="https://github.com/user-attachments/assets/cb90bc34-6c4d-436d-93bc-4b6fb00de7f5"
/>
Since the days weren't useful, the picker has been refactored to remove
the days.
# Miscellaneous
- Fixed a bug with drag and drop edge-case with 2 items in a list.
# Improvements
## Lots of chained operations
It would be nice to create small utils to avoid repeated chained
operations, but that is how Temporal is designed, a very small set of
primitive operations that allow to compose everything needed. Maybe
we'll have wrappers on top of Temporal in the coming years.
## Creation of Temporal objects is throwing errors
If the input is badly formatted Temporal will throw, we might want to
adopt a global strategy to avoid that.
Example :
```ts
const newPlainDate = Temporal.PlainDate.from('bad-string'); // Will throw
```
## Fix filter parsing for charts
Fixes https://github.com/twentyhq/twenty/issues/16606
Fixes https://github.com/twentyhq/private-issues/issues/396
When clicking on a chart slice/bar grouped by certain field types, the
filter value was passed as a plain string instead of a JSON array,
causing a JSON parse error on navigation.
This happens because `arrayOfStringsOrVariablesSchema` in the filter
parsing logic expects JSON array format for certain field types, but the
values weren't wrapped correctly for all cases.
Extracted the util `formatChartFilterValue` and renamed it to
`serializeChartBucketValueForFilter` and modified it to handle JSON
array wrapping for:
- CURRENCY fields with currencyCode subfield (IS operand)
- MULTI_SELECT fields (CONTAINS operand)
- ADDRESS fields with addressCountry subfield (CONTAINS operand)
Added unit tests for the new utility

## Summary
UNLISTED views are personal views tied to a specific user, so API keys
should not be able to create them.
## Changes
- Added check in `canUserCreateView` to block API keys from creating
UNLISTED views
- Refactored the service to use smaller functions with early returns (no
nested if/else)
## Behavior Matrix
### Creating Views
| Caller | Visibility | Has VIEWS Permission | Result |
|--------|------------|---------------------|--------|
| User | UNLISTED | (not checked) | ✅ Allow |
| User | WORKSPACE | Yes | ✅ Allow |
| User | WORKSPACE | No | ❌ Denied |
| **API Key** | **UNLISTED** | (not checked) | **❌ Denied** |
| API Key | WORKSPACE | Yes | ✅ Allow |
| API Key | WORKSPACE | No | ❌ Denied |
Fixes#16739
- Remove empty string coercion in createCoreView that caused PostgreSQL
UUID errors for API keys
- Add permission check allowing API keys with VIEWS permission to manage
workspace views they created
API keys with 'Manage Views' permission can now create, update, and
delete workspace views via both GraphQL and REST APIs.

Solves #16015
- Added a check in `useTimelineActivities.ts` to see if the system
object page we're viewing has timelineActivity being tracked before
querying to get the activity history.
- Removed @WorkspaceIsObjectUIReadOnly decorator from system objects and
added @WorkspaceIsFieldUIReadOnly to standard and system fields to allow
custom field edits as requested in the issue.
- Did not add calendarEvents or other system objects to timelineActivity
just yet since keeping track of timeline activity for every one of them
felt counter-intuitive and bloated. In order to determine which objects
need timelineActivity, I think we need to fix the broken views of system
objects first, such as the one in the attached screenshots - a good
number of them are broken. The check I added to
`useTimelineActivities.ts` hook displays timeline activity as empty for
the time - error would not be shown as suggested by Thomas.

- Editing custom fields on calendar events (and other objects without
position fields) crashed with TypeError: Cannot convert undefined or
null to object in sortCachedObjectEdges. This happened because some
cached queries had empty orderBy arrays ([]), and the optimistic effect
tried to sort with them. Objects without position fields returned
empty orderBy arrays when there were no sorts, while objects with
position fields automatically got [{ position: 'AscNullsFirst' }].
The backend always adds { id: 'AscNullsFirst' } as a fallback, but
the frontend didn't match this. So, I added { id: 'AscNullsFirst' } to
the Frontend as default orderBy when there are no sorts and no position
field.

## Summary
Adds comprehensive documentation for the `IS_MULTIWORKSPACE_ENABLED`
configuration variable, which was previously undocumented despite being
a fundamental configuration option that significantly changes how Twenty
behaves.
## Changes
### Self-Host Setup Guide (`setup.mdx`)
Added a new **Multi-Workspace Mode** section that explains:
- **Single-workspace mode (default)**: Only one workspace allowed, first
user gets admin privileges, signups disabled after first workspace
- **Multi-workspace mode**: Multiple workspaces with subdomain-based
URLs (e.g., `sales.your-domain.com`)
- **Related config variables**: `DEFAULT_SUBDOMAIN` and
`IS_WORKSPACE_CREATION_LIMITED_TO_SERVER_ADMINS`
- **DNS configuration**: Wildcard DNS setup for dynamic subdomains
- **Workspace creation restrictions**: How to limit workspace creation
to server admins
### Local Setup Guide (`local-setup.mdx`)
Added an info callout in the environment variables section to make
contributors aware of multi-workspace mode, useful when testing
subdomain-based features.
## Why This Matters
The `IS_MULTIWORKSPACE_ENABLED` variable controls:
- Whether multiple workspaces can exist on a single instance
- URL structure (plain domain vs subdomains)
- First user privileges
- Sign-up behavior after initial setup
- SSO workspace resolution logic
This is critical knowledge for self-hosters who want to run Twenty as a
multi-tenant SaaS.
