TypeError: set_or_delete_subscribe() got an unexpected keyword argument 'id' [10/Mar/2025 08:38:23] "POST /api/users/11/subscribe/ HTTP/1.0" 500 88724

I can't figure out why get_object() expects id and doesn't accept pk ? Ьaybe I'm missing something, but I can't catch it. I need to subscribe to a user or delete them if already subscribed.

def set_or_delete_subscribe(self, request, pk=None):
    user = request.user
    user_to_subscribe = get_object_or_404(User, pk=pk)

    if request.method == 'POST':
        _, created = Subscription.objects.get_or_create(user=user, subscribed=user_to_subscribe)
        if created:
            return Response(status=status.HTTP_201_CREATED)
        return Response(status=status.HTTP_400_BAD_REQUEST)

    if request.method == 'DELETE':
        subscription = Subscription.objects.filter(user=user, subscribed=user_to_subscribe).delete()
        if subscription:
            return Response(status=status.HTTP_204_NO_CONTENT)
