The Traefik job fails to start after uncommenting certain parameters

It seems that the volume configuration for Traefik logs might not be working. Could you please provide guidance on troubleshooting this issue?

        static = 5645
      }

        static = 5646
      }

Is a comma allowed without a following element in array?

What is this config, anyway?

I need logging to be enabled and for the logs to be stored on a persistent storage solution or to have access to the logs for future reference. How should it be done correctly to work?
