https://sonarly.com/issue/19636?type=bug The session storage Redis client throws inside a `.catch()` callback on connection timeout, creating an unhandled promise rejection that crashes the Node.js process. Fix: **Three changes in `session-storage.module-factory.ts`:** 1. **Added `reconnectStrategy` to the Redis client config** — on connection failure, the client will retry with exponential backoff (500ms, 1000ms, ... capped at 5000ms) instead of giving up immediately. This matches the resilience behavior of the `ioredis` client used elsewhere in the codebase (`RedisClientService` with `maxRetriesPerRequest: null`). 2. **Replaced `throw new Error(...)` inside `.catch()` with `logger.error()`** — the original pattern created an unhandled promise rejection (throwing inside `.catch()` produces a new rejected promise with no handler), which crashed the Node.js process. Now the error is logged properly without crashing the server. 3. **Added `redisClient.on('error', ...)` handler** — the node-redis v4 client emits `error` events on connection issues. Without a handler, these become unhandled error events. The handler logs errors at the appropriate level using NestJS Logger. These changes allow the server to survive transient Redis connectivity issues during startup (e.g., pod restarts where Redis isn't immediately available) while providing clear log output for debugging.

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
