## Rationale When an SSE record-update event carries a field the tab's metadata cache doesn't know (someone added a custom field after this tab loaded), `computeOptimisticRecordFromInput` throws `Should never occur, encountered unknown fields …`. The catch in `useTriggerEventStreamCreation` swallows the throw, so the **entire event is discarded** — the tab silently stops reflecting that update. **Production evidence (Sentry):** the `Error while processing SSE message` family — ~860 events / ~480 users in the last 30 days, ongoing ([TWENTY-FRONT-7PD](https://twenty-v7.sentry.io/issues/TWENTY-FRONT-7PD) et al.), with the sampled stack landing exactly on this throw. Related: [TWENTY-FRONT-633](https://twenty-v7.sentry.io/issues/TWENTY-FRONT-633) (903 users). ## Why this is the root cause, not a symptom patch The throw is an assertion that unknown fields "should never occur". That's the correct contract for the 4 local-mutation callers (`useUpdateOneRecord`, `useCreateOneRecord`, `useCreateManyRecords`, `useRunWorkflowVersion`) — there, an unknown field is a programming bug. But for the SSE caller the input comes from the **server**, which can legitimately be ahead of the tab's metadata. Schema convergence is the metadata-event pipeline's job (it flows over the same SSE channel); the record pipeline's job is to tolerate the window. So the fix moves the decision to the right caller instead of weakening the assertion for everyone: - `getUnknownRecordInputFields` — detection logic extracted, shared - mutation callers: still throw (behavior unchanged) - SSE update path: filters unknown fields and applies the rest of the event Dropping the *fields* loses nothing: the tab couldn't render them anyway without the metadata, and the metadata event that follows triggers the proper refresh. ## User impact ~480 users/month currently get silently stale tabs (list/kanban rows not reflecting teammates' updates) whenever any custom field is added while they have Twenty open. After this fix, updates keep flowing; only the not-yet-known field is skipped until metadata converges. ## Test plan - [x] Unit tests for `getUnknownRecordInputFields` (known fields, `__typename`, unknown fields, relation join columns) - [x] Existing `computeOptimisticRecordFromInput` tests cover the unchanged throw path - [ ] CI green https://claude.ai/code/session_01Lyi6zTema2FMVVh8MD6c38 --- _Generated by [Claude Code](https://claude.ai/code/session_01Lyi6zTema2FMVVh8MD6c38)_ <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22474?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

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.
