Are the environment variables set correctly?

I don't really understand python but it seems to me that the application tries to read the environment variable MBSLAVE_DB_DB for the db name and not MBSLAVE_DB_NAME as it is stated in the documentation.

https://github.com/acoustid/mbdata/blob/ea0e7e2af55096b221b54f3c1e59154f9c03583b/mbdata/replication.py#L103 https://github.com/acoustid/mbdata/blob/ea0e7e2af55096b221b54f3c1e59154f9c03583b/mbdata/replication.py#L197

I tried to add MBSLAVE_DB_DB as an environment variable but still for some reason I am getting an error.

The issue I am facing is that although I am setting up the environment variables like this (in a k8s yml file):

containers:
      - name: musicbrainz-db-mirror
        image: leiyiliro/mbslave:1.0  # Specific version of the Docker image
        env:
        - name: MBSLAVE_DB_HOST
          value: musicbrainz-db
        - name: MBSLAVE_DB_PORT
          value: "5432"
        - name: MBSLAVE_DB_NAME
          value: musicbrainz
        - name: MBSLAVE_DB_DB
          value: musicbrainz
          # Used for read and write operations on the MusicBrainz database          
        - name: MBSLAVE_DB_USER
          value: $(POSTGRES_USER)
          # PostgreSQL database password for the general user
        - name: MBSLAVE_DB_PASSWORD
          value: $(POSTGRES_PASSWORD)
          # Used for creating and managing the mbslave database, schema updates, and replication
        - name: MBSLAVE_DB_ADMIN_USER
          value: $(POSTGRES_USER)
          # MusicBrainz Slave admin password for the admin user
        - name: MBSLAVE_DB_ADMIN_PASSWORD
          value: $(POSTGRES_PASSWORD)
        - name: MBSLAVE_MUSICBRAINZ_TOKEN
          value: $(MBSLAVE_MUSICBRAINZ_TOKEN)
        ports:
        - containerPort: 80

The code seems to look for a database with the name of my env variable $(POSTGRES_USER) ,which is "xxxxxx".
