@Kludex hi! I am trying to use this nice library with KServe in kserve/kserve#2782

I am using the following snippet inside KServe's logic to override the Uvicorns access log:

        if access_log_format:
            from asgi_logger import AccessLoggerMiddleware
            # As indicated by the asgi-logger docs, we need to clear/unset
            # any setting for uvicorn.access to avoid log duplicates.
            logging.getLogger("uvicorn.access").handlers = []
            app.add_middleware(
                AccessLoggerMiddleware, format=access_log_format)
            # The asgi-logger settings don't set propagate to False,
            # so we get duplicates if we don't set it explicitly.
            logging.getLogger("access").propagate = False

I need to explicitly set logging.getLogger("access").propagate = False to avoid log duplicates, for example:

127.0.0.1:41344 - - [25/Apr/2023:16:46:57 +0000] "POST /v1/models/test:predict HTTP/1.1" 200 - "-" "curl/7.74.0"
2023-04-25 16:46:57.906 5395 access INFO [log():67] 127.0.0.1:41344 - - [25/Apr/2023:16:46:57 +0000] "POST /v1/models/test:predict HTTP/1.1" 200 - "-" "curl/7.74.0"

The above logs are generated if I don't explicitly set the propagate field. The latter seems to be generated by the log function of middleware.py, so I thought to explicitly set it in AccessLoggerMiddleware logic but when I try to run make test I see a lot of failures. Do you have any suggestion about what's best and/or if I am missing something important?

Thanks in advance!
