로그인 부분에서 sequelize 에러 Error: Include unexpected. 가 뜹니다

안녕하세요 제로초님, 현재 5-14 include와 as, foreign key 강의 보고 있습니다.

다른 게 아니라 로그인 시도시 아래와 같은 에러가 뜹니다.

Executing (default): SELECT `id`, `nickname`, `userId`, `password`, `createdAt`, `updatedAt` FROM `Users` AS `User` WHERE `User`.`userId` = 'degurii';
Error: Include unexpected. Element has to be either a Model, an Association or an object.

혹시 어느 부분이 잘못됐는지 알 수 있을까요?? 깃허브 코드와 비교해봐도 다른 부분을 찾지 못했습니다.

models/user.js

routes/user.js
