Django 403 "detail": "Authentication credentials were not provided." Knox Tokens

Question

I was following this tutorial (https://github.com/bradtraversy/lead_manager_react_django/tree/db45e4f6fc05a3481e7b8a0223e0aab0355a84b6) to make a Django-React-Redux application. I am having trouble with my UserAPI, specifically when making a GET request. Note that I am using knox tokens. As the logout function works fine (this function is a default from knox), I can see that the token is properly generated from the login, as I use this token for logout. I suspect that there is something in my settings.py that is wrong.

The error is: 403: "detail": "Authentication credentials were not provided."

class UserAPI(generics.RetrieveAPIView):
    # this route needs protection
    # need a valid token to view
    permission_classes = [
        permissions.IsAuthenticated,
    ]
    serializer_class = UserSerializer

    def get_object(self):
        return self.request.user

    # Get the registered organizations of the user
    @action(methods=['get'],detail=True)
    def registered_orgs(self,request,*args,**kwargs):
        instance = self.get_object()

        orgs = instance.followed_organizations.all()

        serializer = OrganizationSerializer(orgs,many=True)

        return Response(serializer.data)

Here is my settings file:

I can make a login request using Postman, get the token from knox, and then use it for the logout. However, I cannot call any custom made functions that require some permissions class.

I have looked online for a solution, but have found none.

Here's my Postman request:

Please let me know if there is anything else I can provide to help solve this. Thanks!
