ValueError: min() arg is an empty sequence

This is likely because you have not set up any views in your application yet. Make sure you have added your app to INSTALLED_APPS and that you have configured the url conf and views correctly.

I've created a PR with the goal of making this more obvious in the future. But right now the PR only prevents the min() arg is an empty sequence error, but does not return anything helpful to the browser. encode/django-rest-framework#4649

Believe encode/django-rest-framework#4649 is sufficient to close this for now. Should be (minimally) resolved with the 3.5.3 release.
