sonarly-bot 8a588788b0 fix(auth): relax SAML IdP metadata parsing constraints
https://sonarly.com/issue/41466?type=bug

SAML setup is blocked for some organizations because IdP metadata files are rejected client-side as “Invalid File”. The user cannot complete SSO onboarding from the file upload flow.

Fix: Implemented a targeted frontend parser relaxation so valid IdP metadata variants are no longer rejected as “Invalid File” before the user can proceed.

What changed:
1) `parseSAMLMetadataFromXMLFile` now resolves XML nodes by `localName` instead of a hardcoded prefix allowlist (`md/ns0/ns2/dsig/ds`), so metadata with arbitrary namespace prefixes can be parsed.
2) SSO URL extraction no longer requires the HTTP-Redirect binding specifically. It now selects the first `SingleSignOnService` `Location` that is a valid URL.
3) `entityID` validation was relaxed from `z.url()` to non-empty string (`z.string().min(1)`), allowing valid SAML issuer formats like `urn:...` to parse successfully and prefill the form instead of failing file import.
4) Added a unit test that covers non-standard prefixes, POST-only SSO endpoint metadata, and a non-URL entityID to ensure this regression is prevented.

This keeps failures for truly malformed XML/cert data while accepting legitimate metadata variants that were previously blocked in the upload flow.

Installation

Cloud

The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.

Build an app

Scaffold a new app with the Twenty CLI:

npx create-twenty-app my-app

Define objects, fields, and views as code:

import { defineObject, FieldType } from 'twenty-sdk/define';

export default defineObject({
  nameSingular: 'deal',
  namePlural: 'deals',
  labelSingular: 'Deal',
  labelPlural: 'Deals',
  fields: [
    { name: 'name', label: 'Name', type: FieldType.TEXT },
    { name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
    { name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
  ],
});

Then ship it to your workspace:

npx twenty app:publish --private

See the app development guide for objects, views, agents, and logic functions.

Self-hosting

Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
