Bug Report

Description

Bug Summary:
After updating to a newer version, open-webui stopped working when it tried to migrate something that failed. Restarting the container not helping at all, it's just spamming the error and crashing.

Steps to Reproduce:
Download certain models / profiles it doesn't like and let it try migrating them by an update.

Expected Behavior:
It should work.

Actual Behavior:
It is failing and instead of skipping, crashes entirely.

Environment

  • Open WebUI Version: 0.2.2.

  • Ollama (if applicable): [e.g., 0.1.30, 0.1.32-rc1]

  • Operating System:Ubuntu 22.04

Reproduction Details

Confirmation:

  • I have read and followed all the instructions provided in the README.md.
  • I am on the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.

I'll modify the code to skip the modelfiles that cause errors so you won't have issues with the migration, but basically you had an invalid modelfile.
