Ambiguous logging configuration: The `--log-level (-l)` flag sets the

To configure different log level for file and stderr logging,
remove the `--log-level` flag and use `--stderr-log-level` and/or

Alternatively, remove the `--stderr-log-level` and/or `--file-log-level`
flags to share one single log level across both handlers.
