Please do not open bugs against the develop branch. It is not guaranteed to be stable at any point in time. If you are not actively engaged in developing NetBox, you should be running the master branch only.

going back to 2.6.12 release fixes the issue. Please reopen this, I really think there is something fishy

This seems to be a problem with your installation as I cannot reproduce it on a stock release. You can quickly confirm this on the demo site, which is running v2.7.3. Please ensure that you have the proper version of each dependency installed with pip install -r requirements.txt, and post on the discussion list if you require any further assistance.

Weird, I can confirm the issue comes up with djangorestframework==3.10.3 (starting from 3.10.0 actually), if I downgrade to djangorestframework==3.9.4, it works fine. I use the upgrade script every time I change the requirements.txt or upgrade netbox, so that takes care of the pip install.

For the record, I fixed it by killing my virtual env and recreating it from scratch.
