--- BEGIN ISSUE ---
Problems with own logging configuration
Currently I have the problem that my logging configuration is not accepted everywhere. As soon as the REST server starts (Uvicorn Worker), my logging configuration is ignored. I have created a repo that represents my scenario and also which is configuration used. Maybe my configuration is just wrong. In the model itself, I print out all the loggers and the associated handlers and formatter and can see here that it should actually fit. Do you have any ideas?

Here is my small example repo: https://github.com/JustinDroege/mlserver-logging
