@zhiltsov-max Could you please look at the issue?

[zhiltsov-max]

Hi, thank you for reporting the problem. If I understand correctly, you're trying to make some requests via the Django-provided UI for the backend API. I could reproduce the problem in such a scenario. Please try to use the <host url>/api/swagger/ page for making custom requests as an alternative.

[bryan-pakulski]

Aha using the swagger page worked for me, I was using the Django-UI for mocking up which endpoints I should be targeting, thank you for pointing me in that direction.

I think I should be able to get what I'm after now, appreciate the prompt response @zhiltsov-max

I've updated the issue to reflect that it's an issue on the django ui side.
