title_generation fails with 404: MiniMax /v1 endpoint

[Ilanto]

Bug Description

After the latest Hermes update (Apr 29 2026), the new title_generation auxiliary feature fails with:

Title generation failed: 404 page not found

The error message is literally an HTML 404 page, suggesting the request is hitting a wrong URL.

Environment

• Hermes version: Latest (Apr 29 update)
• Provider: MiniMax (MiniMax-M2.7)
• Config: auxiliary.title_generation.provider: auto
• Platform: macOS

What works

• Main chat works fine — can talk to bot via Telegram without issues
• Vision auxiliary works
• Other auxiliary tasks work

What fails

• title_generation always returns 404 page not found
• Log shows: WARNING agent.title_generator: Title generation failed: 404 page not found
• When failure_callback fires, user receives: ⚠ Auxiliary title generation failed: HTTP 404: 404 page not found

Investigation so far

• Direct curl test: https://api.minimax.io/v1/chat/completions returns 401 with "login fail: Please carry the API secret key"
• Different from the 404 page not found error in the logs
• Main chat works, meaning the auth is OK for the primary endpoint
• title_generation may be using a different code path that hits a wrong endpoint

Expected behavior

title_generation should either work correctly or fail silently (not send error messages to user).

Suggested fix

1. Fix the URL/endpoint path for title_generation with MiniMax provider, OR
2. Add proper error handling so 404 errors do not get sent to user via Telegram, OR
3. Add a config option to disable title_generation entirely

This feature was added in the latest update and users did not opt-in to it — consider making it opt-out instead of opt-in.

Likely duplicate of #17705 — same root cause: MiniMax auxiliary title_generation hits 404 because _to_openai_base_url() rewrites endpoint incorrectly. See also #17387 and #17413 for the underlying aux provider routing issue.

Duplicate of #17405 - same root cause (MiniMax auxiliary 404). Fix is in PR #17467. Closing as upstream fix tracked there.
