Hello matsony_15! With the provided information it's hard to triage this ticket properly. I'm not sure what you mean with "this upload_handlers is immutable".

We would need detailed steps to reproduce the reported issue (a small Django test project would be ideal), and also a clear explanation of what's the expected outcome and what's the result you are getting and why that does not match your expectation.

Also please note that Django 4.2 is on security-fixes only mode so ideally we'd need confirmation that your issue is present in Django 5.0 and/or Django main branch.

Thank you!
Natalia.
