DJANGO ModuleNotFound: INSTALLED_APPNAME во время развертывания gunicorn wsgi

Я настраиваю wsgi.py и DockerFile для развертывания моего приложения django в DigitalOcean, но я получаю следующие ошибки на этапе развертывания после успешной сборки.

У меня есть приложения django, созданные manage.py startapp XXX каждое с именами 'users' и 'documents'. Судя по трассировке ошибок, я думаю, что есть проблема с путем, поскольку он не обнаруживает приложения из моей конфигурации "INSTALLED_APPS"
