If this might related to #142, you might try the workaround mentioned at the end of that thread. You might also look through those same logs for similar messages.

I'm experiencing this as well and have not gotten to the bottom of it.

Hey, the logs should contain additional details after the "Exception in ASGI application", can you share it?

It should look like this:

ERROR:    Exception in ASGI application
Traceback (most recent call last):
  File "/opt/venv/.venv/lib/python3.11/site-packages/uvicorn/protocols/http/httptools_impl.py", line 404, in run_asgi
    result = await app(  # type: ignore[func-returns-value]
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/opt/venv/.venv/lib/python3.11/site-packages/uvicorn/middleware/proxy_headers.py", line 78, in __call__
    return await self.app(scope, receive, send)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[...]

Thanks!

Here is more of the log, thanks for any help.

Thanks for the details, this is bug in the pruning method: it removed the "Move" object and the notification relies on it.

I pushed a fix, if you update, you should be able to see the notifications again.

Keep me updated, thanks!

Awesome, thanks so much. I'll give that a try shortly here.

That did it! Thanks again, my notifications page is back. Appreciate it.

Thanks!
