Meltano - TypeError: argument of type 'int' is not iterable (Solved)

Ran into this when trying to set up imports and exports with Meltano. The bug ended up being an incorrect .yaml config.

I had:

    config:
      host: meltano-test-cluster.[...].rds.amazonaws.com
      port:
        user: [username]
      dbname: [dbname]

Needed to fix to:

    config:
      host: meltano-test-cluster.[...].rds.amazonaws.com
      port: 5432
      user: [username]
      dbname: [dbname]

Easy in retrospect, but the error message isn't particularly descriptive and I couldn't find much on google, so posting this!
