How can I handle authentication errors in Django REST with async support?

You can handle authentication errors in Django REST by using middleware to catch exceptions and return appropriate responses.

What specific exceptions should I look for when implementing this?

You should look for exceptions like AuthenticationFailed, NotAuthenticated, and PermissionDenied.

Can you provide an example of middleware for this?

Sure! Here's a simple middleware example:

from rest_framework.exceptions import AuthenticationFailed, NotAuthenticated, PermissionDenied

class CustomAuthMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        try:
            response = self.get_response(request)
        except (AuthenticationFailed, NotAuthenticated, PermissionDenied) as e:
            return JsonResponse({'error': str(e)}, status=401)
        return response
