I used the following image databack/mysql-backup:51c9ce6e97a5b864bef95767c707896b95a7916b. I omitted DB_PORT: 3306 row in my compose.yaml file and got the following error:

mysql_backup  | time="2024-04-07T18:03:13Z" level=info msg="beginning dump 2024-04-07T18:03:13Z"

mysql_backup exited with code 1

Yeah, looks like it. Easy enough to fix, though.
