https://sonarly.com/issue/28252?type=bug When a user queries an AI chat thread that doesn't exist (deleted, stale reference, or wrong userWorkspaceId), the server returns a 500 InternalServerError instead of a 404 NotFoundError because the code uses the wrong AgentExceptionCode. Fix: Changed all "Thread not found" and "Queued message not found" throw sites in the AI chat module from `AgentExceptionCode.AGENT_EXECUTION_FAILED` to `AgentExceptionCode.AGENT_NOT_FOUND`. **Why:** `AGENT_EXECUTION_FAILED` maps to `InternalServerError` (500) in the GraphQL exception handler. Missing threads/messages are a normal not-found condition, not an execution failure. `AGENT_NOT_FOUND` already exists and correctly maps to `NotFoundError` (404) in both the GraphQL handler and REST filter. **7 sites fixed across 4 files:** - `agent-chat.service.ts`: `getThreadById()` and `getMessagesForThread()` - `agent-chat-streaming.service.ts`: `streamAgentChat()` - `agent-chat.resolver.ts`: `sendChatMessage()`, `deleteQueuedChatMessage()` (2 checks: queued message + thread) - `agent-chat-subscription.resolver.ts`: `onAgentChatEvent()` This stops the `GetChatMessages` query (and all other chat operations) from producing 500 errors when a thread is not found, reducing Sentry noise and returning correct HTTP semantics to the frontend.

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.
