## Summary
- `SettingsApplicationCustomTab` renders `FrontComponentRenderer` which
calls `useFrontComponentExecutionContext` →
`useLayoutRenderingContext()`, but the settings page never provided a
`LayoutRenderingProvider`
- Every other render site (side panel, command menu, record pages) wraps
`FrontComponentRenderer` with this provider — it was just missed here
- Opening the "Custom" tab in Settings → Applications crashes with:
`LayoutRenderingContext Context not found`
- Fix: wrap with `LayoutRenderingProvider` using `DASHBOARD` layout type
and no target record, matching the pattern used in
`SidePanelFrontComponentPage`
## Test plan
- [ ] Open Settings → Applications → any app with a custom settings tab
- [ ] Click the "Custom" tab — should render the front component without
crashing

## What changed
This refactor fixes AI chat error surfacing by aligning both the backend
and frontend with the existing GraphQL error architecture instead of
adding AI-local error translation.
On the backend:
- add a dedicated GraphQL billing exception path
- register billing GraphQL handling globally for GraphQL requests
- reuse the existing AI GraphQL interceptor path for agent/chat
exceptions
- keep billing status classification shared between REST and GraphQL
- remove the earlier attempt to preserve `CustomException` metadata in
the global GraphQL fallback
On the frontend:
- keep the original Apollo GraphQL error object in AI chat state
- reuse shared Apollo/GraphQL helpers for user-facing messages and
error-type checks
- delete AI-specific error extraction helpers that duplicated generic
GraphQL parsing
- replace a few direct `extensions.subCode` call sites with a shared
predicate
## Why it changed
The original bug was that `BillingException` and AI exceptions thrown
from chat were not being translated into GraphQL errors with the
expected `extensions.subCode` and `extensions.userFriendlyMessage`, so
the AI chat UI had nothing structured to inspect.
An intermediate fix worked mechanically but pushed `CustomException`
handling into the global GraphQL fallback, which blurred the intended
layering. This PR moves the behavior back to explicit GraphQL edges.
## Root cause
`AgentChatResolver` could throw `BillingException` and `AgentException`,
but:
- billing had a REST exception filter and no shared GraphQL equivalent
- AI chat was not consistently using the same GraphQL exception
translation path as the sibling AI resolver
- the frontend chat UI had drifted into AI-specific error parsing
instead of consuming the same structured Apollo errors as the rest of
the app
## Impact
- `BILLING_CREDITS_EXHAUSTED` is now preserved through GraphQL and can
render the existing credits-exhausted UI in chat
- `API_KEY_NOT_CONFIGURED` is preserved through the AI GraphQL path
- AI chat now follows the same general GraphQL error consumption pattern
as the rest of the frontend
- billing GraphQL handling is less dependent on individual resolver
authors remembering to add a filter
## Validation
- `yarn jest --config packages/twenty-server/jest.config.mjs
packages/twenty-server/src/engine/core-modules/billing/utils/__tests__/billing-graphql-api-exception-handler.util.spec.ts
packages/twenty-server/src/engine/metadata-modules/ai/ai-agent/utils/__tests__/agent-graphql-api-exception-handler.util.spec.ts`
- `yarn jest --config packages/twenty-front/jest.config.mjs
packages/twenty-front/src/utils/__tests__/is-graphql-error-of-type.util.test.ts`
- `npx oxlint --type-aware ...` on touched backend/frontend files
- `npx prettier --check ...` on touched backend/frontend files
## Follow-up ideas
- consolidate frontend GraphQL error helpers further so more existing
direct `extensions.subCode` checks move to shared utilities
- consider whether common GraphQL exception filter registration should
live in a more explicit GraphQL-specific module instead of
`CoreEngineModule`
- add an end-to-end test for a real `sendChatMessage` GraphQL failure
path in AI chat

## Bug description
Headless command menu items were interpreted as non headless command
menu items and opened in the side panel.
https://github.com/user-attachments/assets/44d8b4d3-9ee5-4f12-9ff8-b3ed51e5b3b6
## Fix
https://github.com/user-attachments/assets/9d6eb900-9817-4ceb-87aa-547ad046a5a1
- Command menu items received via SSE lack the nested `frontComponent`
relation (only `frontComponentId` is present), causing
`item.frontComponent?.isHeadless` to always be undefined.
- Add `frontComponents` to the metadata store's stale entity loading
- Rewrite `commandMenuItemsSelector` to join `commandMenuItems` with
`frontComponents` by `frontComponentId`
## 1. The `twenty-client-sdk` Package (Source of Truth)
The monorepo package at `packages/twenty-client-sdk` ships with:
- A **pre-built metadata client** (static, generated from a fixed
schema)
- A **stub core client** that throws at runtime (`CoreApiClient was not
generated...`)
- Both ESM (`.mjs`) and CJS (`.cjs`) bundles in `dist/`
- A `package.json` with proper `exports` map for
`twenty-client-sdk/core`, `twenty-client-sdk/metadata`, and
`twenty-client-sdk/generate`
## 2. Generation & Upload (Server-Side, at Migration Time)
**When**: `WorkspaceMigrationRunnerService.run()` executes after a
metadata schema change.
**What happens in `SdkClientGenerationService.generateAndStore()`**:
1. Copies the stub `twenty-client-sdk` package from the server's assets
(resolved via `SDK_CLIENT_PACKAGE_DIRNAME` — from
`dist/assets/twenty-client-sdk/` in production, or from `node_modules`
in dev)
2. Filters out `node_modules/` and `src/` during copy — only
`package.json` + `dist/` are kept (like an npm publish)
3. Calls `replaceCoreClient()` which uses `@genql/cli` to introspect the
**application-scoped** GraphQL schema and generates a real
`CoreApiClient`, then compiles it to ESM+CJS and overwrites
`dist/core.mjs` and `dist/core.cjs`
4. Archives the **entire package** (with `package.json` + `dist/`) into
`twenty-client-sdk.zip`
5. Uploads the single archive to S3 under
`FileFolder.GeneratedSdkClient`
6. Sets `isSdkLayerStale = true` on the `ApplicationEntity` in the
database
## 3. Invalidation Signal
The `isSdkLayerStale` boolean column on `ApplicationEntity` is the
invalidation mechanism:
- **Set to `true`** by `generateAndStore()` after uploading a new client
archive
- **Checked** by both logic function drivers before execution — if
`true`, they rebuild their local layer
- **Set back to `false`** by `markSdkLayerFresh()` after the driver has
successfully consumed the new archive
Default is `false` so existing applications without a generated client
aren't affected.
## 4a. Logic Functions — Local Driver
**`ensureSdkLayer()`** is called before every execution:
1. Checks if the local SDK layer directory exists AND `isSdkLayerStale`
is `false` → early return
2. Otherwise, cleans the local layer directory
3. Calls `downloadAndExtractToPackage()` which streams the zip from S3
directly to disk and extracts the full package into
`<tmpdir>/sdk/<workspaceId>-<appId>/node_modules/twenty-client-sdk/`
4. Calls `markSdkLayerFresh()` to set `isSdkLayerStale = false`
**At execution time**, `assembleNodeModules()` symlinks everything from
the deps layer's `node_modules/` **except** `twenty-client-sdk`, which
is symlinked from the SDK layer instead. This ensures the logic
function's `import ... from 'twenty-client-sdk/core'` resolves to the
generated client.
## 4b. Logic Functions — Lambda Driver
**`ensureSdkLayer()`** is called during `build()`:
1. Checks if `isSdkLayerStale` is `false` and an existing Lambda layer
ARN exists → early return
2. Otherwise, deletes all existing layer versions for this SDK layer
name
3. Calls `downloadArchiveBuffer()` to get the raw zip from S3 (no disk
extraction)
4. Calls `reprefixZipEntries()` which streams the zip entries into a
**new zip** with the path prefix
`nodejs/node_modules/twenty-client-sdk/` — this is the Lambda layer
convention path. All done in memory, no disk round-trip
5. Publishes the re-prefixed zip as a new Lambda layer via
`publishLayer()`
6. Calls `markSdkLayerFresh()`
**At function creation**, the Lambda is created with **two layers**:
`[depsLayerArn, sdkLayerArn]`. The SDK layer is listed last so it
overwrites the stub `twenty-client-sdk` from the deps layer (later
layers take precedence in Lambda's `/opt` merge).
## 5. Front Components
Front components are built by `app:build` with `twenty-client-sdk/core`
and `twenty-client-sdk/metadata` as **esbuild externals**. The stored
`.mjs` in S3 has unresolved bare import specifiers like `import {
CoreApiClient } from 'twenty-client-sdk/core'`.
SDK import resolution is split between the **frontend host** (fetching &
caching SDK modules) and the **Web Worker** (rewriting imports):
**Server endpoints**:
- `GET /rest/front-components/:id` —
`FrontComponentService.getBuiltComponentStream()` returns the **raw
`.mjs`** directly from file storage. No bundling, no SDK injection.
- `GET /rest/sdk-client/:applicationId/:moduleName` —
`SdkClientController` reads a single file (e.g. `dist/core.mjs`) from
the generated SDK archive via
`SdkClientGenerationService.readFileFromArchive()` and serves it as
JavaScript.
**Frontend host** (`FrontComponentRenderer` in `twenty-front`):
1. Queries `FindOneFrontComponent` which returns `applicationId`,
`builtComponentChecksum`, `usesSdkClient`, and `applicationTokenPair`
2. If `usesSdkClient` is `true`, renders
`FrontComponentRendererWithSdkClient` which calls the
`useApplicationSdkClient` hook
3. `useApplicationSdkClient({ applicationId, accessToken })` checks the
Jotai atom family cache for existing blob URLs. On cache miss, fetches
both SDK modules from `GET /rest/sdk-client/:applicationId/core` and
`/metadata`, creates **blob URLs** for each, and stores them in the atom
family
4. Once the blob URLs are cached, passes them as `sdkClientUrls`
(already blob URLs, not server URLs) to `SharedFrontComponentRenderer` →
`FrontComponentWorkerEffect` → worker's `render()` call via
`HostToWorkerRenderContext`
**Worker** (`remote-worker.ts` in `twenty-sdk`):
1. Fetches the raw component `.mjs` source as text
2. If `sdkClientUrls` are provided and the source contains SDK import
specifiers (`twenty-client-sdk/core`, `twenty-client-sdk/metadata`),
**rewrites** the bare specifiers to the blob URLs received from the host
(e.g. `'twenty-client-sdk/core'` → `'blob:...'`)
3. Creates a blob URL for the rewritten source and `import()`s it
4. Revokes only the component blob URL after the module is loaded — the
SDK blob URLs are owned and managed by the host's Jotai cache
This approach eliminates server-side esbuild bundling on every request,
caches SDK modules per application in the frontend, and keeps the
worker's job to a simple string rewrite.

- Makes engineComponentKey non-nullable on CommandMenuItem. Adds two new
engine component keys: TRIGGER_WORKFLOW_VERSION and
FRONT_COMPONENT_RENDERER to cover the former standalone cases.
- Unifies the previously separated engine, front component and workflow
runners into a single `CommandRunner` component with a unified
`useMountCommand` hook that handles all command types.
Introduces a progress indicator for command menu items (both engine
commands and front components). When a command is running, the menu item
now displays a percentage alongside the loader spinner instead of just a
spinner.
- Added `commandMenuItemProgressFamilyState` to track per-item progress
and `CommandListItemLoader` to render it
- Exposed `updateProgress` in the twenty-sdk public API so front
components can report execution progress back to the host
- Wired progress reporting into `ExportMultipleRecordsCommand` as the
first consumer, showing CSV export progress
- Progress state is cleaned up on unmount for both engine commands and
headless front components
- Refactor
## Description
- Introduces a new engine command execution model that replaces the
previous approach of mapping `EngineComponentKey` to React components.
Instead, engine commands are now mounted headlessly via
`HeadlessEngineCommandMountRoot`, with their execution context populated
synchronously before mounting.
- Creates new headless command components
- Moves error handling from the SDK layer to the host app by wrapping
all mounted commands with a new `CommandMenuItemErrorBoundary`
The new flow works as follows:
- When a command menu item with an `engineComponentKey` is clicked,
`useCommandMenuItemFrontComponentCommands` calls
`useMountEngineCommand`, which synchronously reads the current context
store (object metadata, selected records, filters, view ID, etc.) and
writes a `MountedEngineCommandContext` into
`mountedEngineCommandsState`.
- The command is then mounted into `mountedEngineCommandsState`, which
triggers `HeadlessEngineCommandMountRoot` to render the corresponding
headless component from `ENGINE_COMPONENT_KEY_HEADLESS_COMPONENT_MAP`,
wrapped in `CommandMenuItemErrorBoundary`,
`ContextStoreComponentInstanceContext.Provider`, and
`EngineCommandComponentInstanceContext.Provider`.
- Each command component reads its execution context and delegates to
one of the 4 execution patterns: `HeadlessEngineCommandWrapperEffect`
(simple actions), `HeadlessConfirmationModalEngineCommandEffect`
(destructive actions needing confirmation),
`HeadlessNavigateEngineCommand` (GO_TO_* commands), or
`HeadlessOpenSidePanelPageEngineCommand` (SEARCH_RECORDS, ASK_AI,
VIEW_PREVIOUS_AI_CHATS).
- After execution, the command self-unmounts via
`useUnmountEngineCommand`, which removes the entry from
`mountedEngineCommandsState` and stops rendering the component.
## Summary
This PR upgrades Apollo Client from v3.10.0 to v4 and refactors error
handling patterns across the codebase to use a new centralized
`useSnackBarOnQueryError` hook.
## Key Changes
- **Dependency Update**: Upgraded `@apollo/client` from `^3.10.0` to
`^3.11.0` in root package.json
- **New Hook**: Added `useSnackBarOnQueryError` hook for centralized
Apollo query error handling with snack bar notifications
- **Error Handling Refactor**: Updated 100+ files to use the new error
handling pattern:
- Removed direct `ApolloError` imports where no longer needed
- Replaced manual error handling logic with `useSnackBarOnQueryError`
hook
- Simplified error handling in hooks and components across multiple
modules
- **GraphQL Codegen**: Updated codegen configuration files to work with
Apollo Client v3.11.0
- **Type Definitions**: Added TypeScript declaration file for
`apollo-upload-client` module
- **Test Updates**: Updated test files to reflect new error handling
patterns
## Notable Implementation Details
- The new `useSnackBarOnQueryError` hook provides a consistent way to
handle Apollo query errors with automatic snack bar notifications
- Changes span across multiple feature areas: auth, object records,
settings, workflows, billing, and more
- All changes maintain backward compatibility while improving code
maintainability and reducing duplication
- Jest configuration updated to work with the new Apollo Client version

## Summary
Removes the `recoil` dependency entirely from `package.json` and
`twenty-front/package.json`, completing the migration to Jotai as the
sole state management library.
Removes all Recoil infrastructure: `RecoilRoot` wrapper from `App.tsx`
and test decorators, `RecoilDebugObserver`, Recoil-specific ESLint rules
(`use-getLoadable-and-getValue-to-get-atoms`,
`useRecoilCallback-has-dependency-array`), and legacy Recoil utility
hooks/types (`useRecoilComponentState`, `useRecoilComponentValue`,
`createComponentState`, `createFamilyState`, `getSnapshotValue`,
`cookieStorageEffect`, `localStorageEffect`, etc.).
Renames all `V2`-suffixed Jotai state files and types to their canonical
names (e.g., `ComponentStateV2` -> `ComponentState`,
`agentChatInputStateV2` -> `agentChatInputState`, `SelectorCallbacksV2`
-> `SelectorCallbacks`), and removes the now-redundant V1 counterparts.
Updates ~433 files across the codebase to use the renamed Jotai imports,
remove Recoil imports, and clean up test wrappers (`RecoilRootDecorator`
-> `JotaiRootDecorator`).
## PR description
- Adds `enqueueSnackbar` to the front component host communication API,
allowing front components to display snack bar notifications (success,
error, info, warning) to the user.
- Introduces `frontComponentId` to the `FrontComponentExecutionContext`
and a `useFrontComponentId` hook, enabling front components to identify
themselves (used for dedupe keys).
- Wires error/success notifications into the `Action`, `ActionLink`, and
`ActionOpenSidePanelPage` SDK components -> actions now catch errors and
display them as snack bars, and `Action` supports an optional
`notifyOnEnd` prop for success feedback.

## Description
- Add `isHeadless` field to `FrontComponent` entity so front components
can run without rendering UI in the command menu
- Introduce headless front component mounting logic:
`HeadlessFrontComponentMountRoot` at the application root,
`useMountHeadlessFrontComponent`, and `useUnmountHeadlessFrontComponent`
hooks to mount/unmount headless components
- Expand the SDK with new action components (`Action`, `ActionLink`,
`ActionOpenSidePanelPage`) and host communication functions
(`openSidePanelPage`, `unmountFrontComponent`)
- Move `CommandMenuPages` type to twenty-shared so the SDK can reference
it for side panel navigation

Create the necessary tooling to listen to metadata events and plug it to
the front components. Now we have a hot reload like experience when we
edit a component in an app.
## Backend
- Split `EventWithQueryIds` into `ObjectRecordEventWithQueryIds` and
`MetadataEventWithQueryIds`
- Publish metadata event batches to active SSE streams in
`MetadataEventsToDbListener`
## Frontend
- Create a metadata event dispatching pipeline: SSE metadata events are
grouped by metadata name, transformed into
`MetadataOperationBrowserEventDetail` objects, and dispatched as browser
`CustomEvents`
- Add `useListenToMetadataOperationBrowserEvent` hook for consuming
metadata operation events filtered by metadata name and operation type
- Rename `useListenToObjectRecordEventsForQuery` to
`useListenToEventsForQuery`, now accepting both
`RecordGqlOperationSignature` and `MetadataGqlOperationSignature`
- Implement `useOnFrontComponentUpdated` which subscribes to front
component metadata events and updates the Apollo cache when the
component is modified
- Add `builtComponentChecksum` to the front component query and appends
it to the component URL for browser cache invalidation
## Split twenty-sdk build into separate Node and browser targets
The SDK was bundling Node.js code (CLI, SDK API) and browser code (UI
components, front-component renderer) through a single Vite config. This
caused incorrect externalization — Node builtins leaked into browser
bundles and browser-specific chunking logic applied to CLI output.
This PR splits the build into `vite.config.node.ts` and
`vite.config.browser.ts` so each target gets the right externals and
output format.
Also includes a few housekeeping renames:
- `front-component` export path → `front-component-renderer` (matches
what it actually is)
- `front-component-common` merged into `front-component-api` (was a
needless extra module)
- Pass the auth token to worker
- Fetch the file from the rest API with the auth token
- Create the blob url
- Update the stories to pass a fake token which will be ignored

- Introduces a SerializedEventData type that captures only serializable
properties from DOM/React events
- Updates `wrapEventHandler` in the host component registry to serialize
native events via serializeEvent() before passing them across the worker
boundary via postMessage, avoiding circular references and non-cloneable
DOM nodes
- Updates generated remote element event signatures to use
RemoteEvent<SerializedEventData> instead of bare RemoteEvent, giving
front-component authors typed access to event details
## PR Description
This PR:
- Introduces a `FrontComponentHostCommunicationApi`, which allows us to
pass functions to be executed from the worker
- Exposes a navigate function from the host to the front component
remote workers, enabling SDK components to trigger in-app navigation
- Gets rid of `useSyncExternalStore` and makes the execution context
reactive without it
- Refactors and improves the `esbuild` plugin system
