weird behaviour with uvicorn

[samuelcolvin]

Description

If I run uvicorn normally (e.g. uv run uvicorn app:app), I see two logs, one from logfire and one from uvicorn

16:11:29.487 GET /
INFO:     172.17.0.1:59302 - "GET / HTTP/1.1" 404 Not Found

If I run uvicorn with --log-level warning, then I see neither. This seems wrong.

I can't reproduce. It works fine here.
