New issue. __call__() missing 2 required positional arguments: 'environ' and 'start_response' #153. Last evening i was getting an error, error being: TypeError: Flask. __call__() missing 1 required positional argument: 'start_response'  Пытаюсь сделать так, что бы по ендпоинту можно было как передать аргументы так и просто Either positional or keyword arguments can be given, not both. Is there a way to get a more informative error than "init() missing 1 required positional argument: 'model'"? import forms Traceback (most recent call last): For `foo(a, /, b)`, it could be: "TypeError: foo() missing 1 required argument 'a', and one required positional argument 'b'.
