Django: TypeError: объект «ListSerializer» не повторяется

Question

Я публикую несколько значений в моем «KeyboardEventView» ModelViewSet. Сообщение успешно, и я вижу, что данные в базе данных регистрируются правильно. Тем не менее, я получаю сообщение об ошибке от Django,

Это сводит меня с ума. Это работает, но надоедливо видеть ошибки. Кто-нибудь еще испытывает это?
