await 관련 질문드립니다.

안녕하세요. 강의 잘 듣고있습니다. 

다름이 아니라 강의에 나온 내용대로 실습을 진행하고 있는데,

await 구문에서 에러가 발생하여 문의합니다. 

const express = require('express');
const bcrypt = require('bcrypt');
const passport = require('passport');

const { User } = require('../models');


const router = express.Router();

// POST /auth/join
router.post('/join', (req, res, next) => {
    const { email, nick, password } = req.body;
    try {
        const exUser = await User.find( { where: { email } });
        if (exUser) {
            req.flash('joinError', '이미 가입된 이메일입니다.');
            return res.redirect('/join');
        }
        const hash = await bcrypt.hash(password, 12);
        await User.create({
            email,
            nick,
            password: hash
        });
        return res.redirect('/');
    } catch (error) {
        console.log(error);
        next(error);
    }
});

package.json 버전입니다.

"dependencies": {
  "bcrypt": "^5.0.0",
  "connect-flash": "^0.1.1",
  "cookie-parser": "^1.4.5",
  "dotenv": "^8.2.0",
  "express": "^4.17.1",
  "express-session": "^1.17.1",
  "morgan": "^1.10.0",
  "mysql2": "^2.1.0",
  "passport": "^0.4.1",
  "passport-kakao": "^1.0.0",
  "passport-local": "^1.0.0",
  "pug": "^3.0.0",
  "sequelize": "^5.21.13"
},

실행하면  아래와 같이 await 구문에 async함수가 아니라고 나오는데요..  bcryt.hash 함수도 마찬가지 입니다. 

어떻게 처리해야 할까요? 

[nodemon] starting `node app.js`
