Server fails to serialize Regex pattern

[George-Miao]

I have following ranking settings in my settings.json:

// ...
"ranking": {
  // ...
  "preferred": [ 
    "BluRay" 
  ],
  // ...
}

However, when I request /settings/ranking, I get an 500 error. Server logs show:

   File "/app/.venv/lib/python3.11/site-packages/fastapi/_compat.py", line 149, in serialize
