Django - BaseSerializer.is_valid() принимает 1 позиционный аргумент, но было задано 2

Этот проект работал раньше, но потом Heroku убрал бесплатный уровень, поэтому я пытался развернуть его в другом месте, но теперь внезапно я не могу даже создать пользователя локально, хотя раньше мог... Теперь, когда я создаю пользователя, я получаю ошибку, указанную в заголовке.
