오류가 이렇게 나옵니다...

하지만 저는 auth.js 설정이 되어있습니다.

const express = require('express');
const passport = require('passport');
const bcrypt = require('bcrypt');
const { isLoggedIn, isNotLoggedIn } = require('./middlewares');
const { User } = require('../models');

const router = express.Router();

// POST /auth/join (회원가입)
router.post('/join', isNotLoggedIn, async (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');
          }
        // console.time('암호화 시간');
        const hash = await bcrypt.hash(password, 17);
        // console.timeEnd('암호화 시간');
        await User.create({
            email,
            nick,
            password: hash,
        });
        return res.redirect('/');
    } catch (error) {
        console.error(error);
        next(error);
    }

})



models/user.js도 이렇게 설정이 되어있습니다.

// 사용자 테이블
module.exports = ( (sequelize, DataTypes) => (
    sequelize.define('user', {
        email : {
            type: DataTypes.STRING(40),
            allowNull: true,
            unique: true,
        },
        nick : {
            type: DataTypes.STRING(15),
            allowNull: false,
        },
        password: {
            type: DataTypes.STRING(100),
            allowNull: true, // 카카오 로그인 위해서 true를 해준다. 나중에 데이터베이스 확인할 것.
        },
        // provider는 local과 kakao 구분하기 위해서
        provider: {
            type:DataTypes.STRING(10),
            allowNull: false,
            defaultValue: 'local',
        },
        snsID: {
            type: DataTypes.STRING(30),
            allowNull: true,
        }
    }, {
        timestamps : true,
        paranoid : true,
    })
));



제대로 적었다고 생각했었는데 User.find 가 없다고 하네요 . 
참고로 회원가입할 때 생기는 오류입니다.

깃허브 필요하시면 첨부해드릴게요!!
