Hi all, using Meltano's Docker image I set up env vars in the

meltano.yml

file to utilize dynamically created database connections (using docker compose) cross-projects. This worked like a charm in

v2.12.0

, however since

v2.13.0

I'm receiving an exception during the

meltano install

step in the Dockerfile. This exception occurs:

invalid literal for int() with base 10: ''

For example, the

meltano.yml

contains the following loader:

loaders:
  - name: target-postgres
    variant: transferwise
    pip_url: pipelinewise-target-postgres
    config:
      host: ${DB_HOST}
      port: ${DB_PORT}
      user: ${DB_USER}
      password: ${DB_PASS}

And in the

docker-compose.yml

I set up the env vars:

services:
  meltano:
    <<: *meltano-image
    command: ui
    environment:
      DB_HOST: ${DB_HOST}
      DB_PORT: ${DB_PORT}
      DB_USER: ${DB_USER}
      DB_PASS: ${DB_PASS}

If I remove the env vars from the

meltano.yml

, the exception doesn't occur. Is this changed intentionally in

v2.13.0

?

@Will Da Silva (Arch) I suspect that’s related to this change, correct? https://github.com/meltano/meltano/pull/7123

That seems likely. I was just looking through the PR to see what might be causing that.

Sure, thanks for the quick replies guys!

Thank you for the detailed bug report @janick_otten!
