    raise ImproperlyConfigured(msg.format(name=self.urlconf_name)) from e
django.core.exceptions.ImproperlyConfigured: The included URLconf 'app.urls' does
not appear to have any patterns in it. If you see the 'urlpatterns' variable with 
valid patterns in the file then the issue is probably caused by a circular import.
