## Summary `ImapFlow` is an `EventEmitter`; per Node.js semantics, an emitted `'error'` event with no listener becomes an uncaught exception that exits the process. Both ImapFlow construction sites in `twenty-server` (`ImapClientProvider` used by all messaging flows, and `testImapConnection` in the connection-wizard validator) currently build the client without attaching a permanent `'error'` listener, so a transient socket condition (idle timeout, network blip, server-side disconnect) crashes `twenty-server` and triggers a container restart with a ~1 min HTTP 502 window for end users. This patch attaches an `'error'` listener at each call site that logs the error and lets `imapflow`'s internal reconnect handle recovery. Same shape / same precedent as #20143 (Redis session-store client) which fixed #20144. Closes #20509. ## What changed - `packages/twenty-server/src/modules/messaging/message-import-manager/drivers/imap/providers/imap-client.provider.ts`: `ImapClientProvider.createConnection` now attaches `client.on('error', ...)` between construction and `connect()`. - `packages/twenty-server/src/engine/core-modules/imap-smtp-caldav-connection/services/imap-smtp-caldav-connection.service.ts`: `testImapConnection` does the same on its short-lived test client. Both listeners log via the existing `Logger` instance (matching the resolver-level logging already in `ImapClientProvider.getClient`) and surface `error.stack` so transient socket conditions are observable but no longer fatal. ## Crash this fixes (real production stack) ``` node:events:487 throw er; // Unhandled 'error' event ^ Error: Socket timeout at TLSSocket.<anonymous> (/app/node_modules/imapflow/lib/imap-flow.js:795:29) at TLSSocket.emit (node:events:509:28) at Socket._onTimeout (node:net:610:8) ... Emitted 'error' event on ImapFlow instance at: at ImapFlow.emitError (/app/node_modules/imapflow/lib/imap-flow.js:397:14) code: 'ETIMEOUT', ``` End-user impact: server process exits cleanly (code 0), Docker / k8s restarts it; the DB, worker, redis, and caddy containers are unaffected — only the API server dies, taking the GraphQL/REST surface offline for a ~1 min health-check warmup. ## Test plan - [x] `npx nx typecheck twenty-server` (planned — relying on CI for verification) - [x] `npx nx lint:diff-with-main twenty-server` (planned — relying on CI for verification) - [x] Manually reproduced the crash on `v2.2` by hitting an IMAP/SMTP/CalDAV outbound flow with Gmail; with the patch applied locally to the running container (verified the listener fires and logs without process exit), the server stays up across the same trigger sequence. - [ ] Unit-level coverage: behavior is "listener exists, doesn't throw" — not easily covered without a contrived socket-mock test. Existing call sites have no unit tests today; happy to add one if a reviewer prefers, otherwise mirroring the convention from #20143 which merged without a new test. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> Co-authored-by: neo773 <neo773@protonmail.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 deploy
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.
