Startup info logs missing from uvicorn after the launch of the app

[sonic-needlemouse]

After the command uvicorn dcb_record_linker.server:app --host 127.0.0.1 --port 4372 I observe this output in logs:

/home/xxxx/yes/envs/reli/lib/python3.9/site-packages/dask/dataframe/_pyarrow_compat.py:23: UserWarning: You are using pyarrow version 11.0.0 which is known to be insecure. See https://www.cve.org/CVERecord?id=CVE-2023-47248 for further details. Please upgrade to pyarrow>=14.0.1 or install pyarrow-hotfix to patch your current version.

But I expect these messages (start up information) in logs:

At the same time, if I go to the host:port/docs page and send requests in the logs, I see info logs from uvicorn:
