Comment:

 I was able to reproduce the error using the steps you provided. It seems
 like the bug is that we're not properly guarding to ensure we're setting
 DATA_UPLOAD_MAX_MEMORY_SIZE as an integer, so I added a guard for it and
 added a test in this [https://github.com/django/django/pull/17618 PR]. The
 new result of the bug will be:
