@TElphee01 Correct, it is set in entrypoint under the compose/django directory. If you want to run a command like shell, you’ll need to do docker-compose -f local.yml run --rm django python manage.py shell

@habenhkt are you aware that you are asking a question in a closed Issue? Besides that, the issue section of github is for issues concerning the project. Your problem is more suitable for in QA site like stackoverflow or the discussion section.

Regarding your question, check the env() method, it is missing the keyword default (settings.py, line 293).
