Is there an existing issue for this?

• 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

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:

... 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

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)
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
