Я пытаюсь зарегистрировать нового пользователя, но возвращаю ошибку «Ошибка типа: не удается преобразовать неопределенный или нулевой в объект». Я знаю, что здесь есть несколько сообщений об этом, но я не могу, возможно, из-за того, что трачу много времени на сосредоточение и усталость. Извините, что создал еще один пост для этого.

 import Sequelize from 'sequelize';
