Error Session ID Guide

When reporting an API error, include the CCH session id so maintainers can locate the exact request.

Where to find it

Preferred: response header x-cch-session-id
Fallback: error.message suffix cch_session_id: <id>

If the response does not include a session id, the server could not determine it for that request.

Example (curl)

curl -i -sS \\
  -H "Authorization: Bearer <your-key>" \\
  -H "Content-Type: application/json" \\
  -d '{"model":"gpt-4.1-mini","messages":[{"role":"user","content":"hi"}]}' \\
  http://localhost:13500/v1/chat/completions

In the response:

Check header: x-cch-session-id: ...
If missing, check JSON: {"error":{"message":"... (cch_session_id: ...)"} }
