Description

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 the 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.

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.
