Description

I encountered the following error with django 4.1 in my Gitlab CI/CD Pipeline. When I bumped django versions from 4.0.7 to 4.1. my pipeline broke during the testing stage; specifically during db migrations. I have not changed any other source code.

Steps to reproduce

Minimal example attached. Run make green to see that it works with 4.0.7, run make red to see that it does not work with 4.1. It will build and exercise a docker container which installs all dependencies in isolation and sets up an example django app and run migrations.

Manual steps:

  1. Install django 4.1
  2. Create a new project
  3. Create an app
  4. Install app in project
  5. Create a model
  6. Add field on model
  7. Make migrations
  8. Remove field
  9. Make migrations

The migration should fail.
