### Is there an existing issue for this? - [x] I have searched the existing issues ### Current Behavior When using the new "Tasks" tab, after the workspace is created and code-server is ready, the left part (chat?) shows: ``` "user" must be an existing uuid or username. queried user="chat" ``` I think this might be due to the fact that I logged in via GitHub (?) and this is the open source edition <img width="856" height="360" alt="Image" src="https://github.com/user-attachments/assets/6fe09bb1-1941-4071-80f4-66b074f23133" /> The path of the HTTP call is: `/api/v2/users/chat/workspace/embed?include_deleted=true` Additionally, when starting one of the workspaces with Claude Code: <img width="1251" height="247" alt="Image" src="https://github.com/user-attachments/assets/6780c678-d550-4452-aec3-80503738ac1c" /> ... the "Claude Code Web" link opens a tab pointing at `/chat/embed` - but that returns a similar error: > "user" must be an existing uuid or username. > queried user="chat" ### Relevant Log Output ```shell ``` ### Expected Behavior A chat appears on the left side and no error shows up in the developer console ### Steps to Reproduce 1. Create a template that uses the new coding agents (see for example [claude-code](https://registry.coder.com/modules/coder/claude-code)) 2. Create a new task, type anything 3. Wait for the workspace to be ready, you should see the error on the left side ### Environment - Host OS: Alpine Linux - Kubernetes - Coder version: ghcr.io/coder/coder:v2.24.1 ### Additional Context The issue occurs consistently
