Я делаю DRF api и получаю сообщение TypeError, когда пытаюсь сделать запрос.

Это сообщение не позволяет мне даже отладить.

Я ищу способ и проверил settings.REST_FRAMEWORK.

Это адрес моего кода проекта: https://github.com/jeonyh0924/WPS_DabangAPI/tree/d13d6b440d2a5a1dfd3e17318bee14d02544f6a5

Я изучаю через соответствующие адреса:
