TypeError: Router.use() requires a middleware function but got a Object

 

const express= require('express');
const router = express.Router();

router.use('/getboardlist', require('./getboardlist'));
router.use('/addboard', require('./addboard'));

 

routes 폴더 파일 내 위와 같이

module.exports=router

를 작성하지 않아 발생하는 에러이다.
