📄 Description

Before submitting, make sure you have checked the following:

  • Linked Issue/Discussion: Closes [PR #17932] [CLOSED] Update Base (#24604)
  • Target branch: The pull request targets the dev branch.
  • Description: A concise description of the changes is provided below.
  • Git Hygiene: The PR is atomic (one logical change), rebased on dev, and contains no unrelated commits.
  • Title Prefix: fix

Description

When the frontend sends an empty or missing model_id (e.g., when clicking the title regenerate icon on a chat with no model assigned), the backend now gracefully falls back to the first available model instead of returning a 404 MODEL_NOT_FOUND error. This fix is applied consistently across all 7 task endpoints in tasks.py.

Fixed

  • Auto-title generation no longer errors on chats without a model assigned
  • Graceful fallback to first available model when model_id is empty or not found
  • Consistent fix across all task endpoints (title, follow-up, query, image_prompt, emoji, tags, MOA)
