34430	Custom exception handler not called	frontierconnect	nobody	" coded my own method custom_exception_handler for exception handling but for authentication exception this callback is not called

I configured in my settings the callback under:

REST_FRAMEWORK = {'EXCEPTION_HANDLER' : 'myapp.api.response.custom_exception_handler',}

Simple performing a api call without token (that requires auth), it is raised NotAuthenticated exception, that is returning on Response

{""detail"":""Authentication credentials were not provided.""}

My view class is inherited from rest_framework.viewsets.GenericViewSet that inherits APIView

I noticed that the exception handler callback is managed in APIView

exception_handler = self.get_exception_handler()

that returns settings.EXCEPTION_HANDLER that pointing to default rest_framework exception handler. 

Seems that REST_FRAMEWORK configuration is not taken into account.
