codemie assistants chat fails with misleading "Authentication expired" error despite valid, freshly-refreshed SSO session

[yaoweikwek]

Description

The codemie assistants chat command fails with a misleading "Authentication expired" error when chatting with any registered CodeMie assistant, even immediately after a fresh, successful SSO token refresh. The main coding LLM (chat/completions) works fine — only the assistants chat subcommand is affected.

Steps to Reproduce

1. Have one or more assistants registered (e.g. via codemie assistants registration), tied to a CodeMie project.
2. Run codemie profile refresh — this succeeds and confirms a valid SSO session (verified with codemie profile status, showing ~24h remaining).
3. Run codemie assistants chat <assistant-id> "hello test".
4. Observe the failure. Retrying immediately, with a different assistant ID, or in a clean environment (env -i) produces the identical error every time.

Expected Behavior

The assistant chat should succeed using the valid, freshly-refreshed SSO session — same as the main coding chat, which works without issue.

Actual Behavior

- Loading configuration...
✔ Connected to CodeMie

✗ undefined

❌ Authentication expired. Please re-authenticate.

This happens consistently, regardless of:

• Refreshing the SSO token right before retrying (codemie profile refresh → immediate retry)
• Which registered assistant ID is targeted (reproduced with two different assistants)
• Running in a clean environment stripped of extra env vars

Additionally, the debug logs do not capture the real error detail — the underlying error object is logged as the literal string [object Object] instead of being serialized, so the true HTTP status/response body is lost:

[ERROR] [system] [] Assistant chat API call failed [object Object]
[ERROR] [system] [] Failed to chat with assistant [object Object]

This makes it impossible for users (or maintainers reviewing logs) to determine the real cause (e.g. a 403 permission issue vs. genuine auth expiry).
