Solution

  • Probably could be solved with the procfile:

    web: gunicorn app.app:app

    Although for clarity you may wish to rename the top-level app folder to something different, then have:

    web: gunicorn something.app:app

    Or create a something/__init__.py file with the contents:

    from .app import app

    Then simply have a procfile with:

    web: gunicorn something:app
