Re: django.db.migrations.graph.NodeNotFoundError:

Hi,

Do you want to copy and paste your error message? (I assume it's similar, but it might have some better clues.)

My guess you have a migration that's referencing a migration file that was deleted or something.

I have the same problem, but with an existing project. I've deleted migrations and the database and shows the same problem.

I have 2+ hours searching but I haven't fixed it.
