Closes #18928 ## Problem When a JWT access token expires while the AI chat is streaming a response, the SSE connection drops and `graphql-sse` calls the retry callback. The previous implementation would wait, then destroy the SSE client but never refreshed the token. On the next connection attempt the client reused the same expired token, eventually triggering an `UNAUTHENTICATED` error that redirected the user to the login screen. ## Solution Add proactive token renewal inside `useHandleSseClientConnectionRetry` before each reconnect attempt: - Uses a module-level `let renewalPromise` variable to deduplicate concurrent renewal requests , the exactpattern used in `ApolloFactory.ts` - Calls `renewToken` via `retryWithBackoff` against the `/metadata` endpoint - Writes the fresh token pair into the Jotai store ,the SSE client's `headers()` callback picks it up automatically on reconnect - If renewal fails -> falls back to destroying the SSE client as before ## Files changed - `packages/twenty-front/src/modules/sse-db-event/hooks/useHandleSseClientConnectionRetry.ts` ## Notes This addresses the two issues from the previous review: - No `useRef` using module-level variable instead - CI passing removed the `CombinedGraphQLErrors` import --------- Co-authored-by: Etienne <45695613+etiennejouan@users.noreply.github.com>

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.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
