Cannot read property 'passport' of undefined

TypeError: Cannot read property 'passport' of undefined

И я не могу понять, почему она не работает.

Вот мой app.js: 

const createError = require('http-errors');
const express = require('express');
const path = require('path');
const cookieParser = require('cookie-parser');
const logger = require('morgan');
const session = require('express-session');
const passport = require('passport');
const Account = require('./models/account');
const LocalStrategy = require('passport-local').Strategy;

const indexRouter = require('./routes/index');
const usersRouter = require('./routes/users');

const app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

app.use('/', indexRouter);
app.use('/users', usersRouter);

app.use(session({
  cookieName: 'session',
  secret: 'hamzasaucegod',
  resave: false,
  saveUninitialized: false
}));

app.use(passport.initialize());
app.use(passport.session());
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

passport.use(new LocalStrategy(Account.authenticate()));

passport.serializeUser(Account.serializeUser());
passport.deserializeUser(Account.deserializeUser());


// catch 404 and forward to error handler
app.use(function(req, res, next) {
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

Вот мой файл account.js: 

const passport = require('passport');

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const passportLocalMongoose = require('passport-local-mongoose');

const Account = new Schema({
    username: String,
    password: String
});

Account.plugin(passportLocalMongoose);

module.exports = mongoose.model('Account', Account);

И, наконец, вот мой файл index.js, который содержит ошибку, которую я считаю: 

const express = require('express');
const passport = require('passport');
const Account = require('../models/account');

const router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Dashboard', user : req.user, error : null });
});

router.get('/register', function(req, res) {
  if ( req.session.passport.user != null ) {
    res.redirect('/');
  } else {
    res.render('register', {
      title : 'Sign-up'
    });
  }
});

router.post('/register', function(req, res, next) {
  Account.register(new Account({ username : req.body.username }), req.body.password, function(err, account) {
    if (err) {
      return res.render('register', { error : err.message });
    }

    passport.authenticate('local')(req, res, function () {
      req.session.save(function (err) {
        if (err) {
          return next(err);
        }
        res.redirect('/');
      });
    });
  });
});

router.get('/login', function(req, res) {
  if ( req.session.passport.user != null ) {
    res.redirect('/');
  } else {
    res.render('login', {
      user : req.user,
      title : 'Sign-in',
      subTitle : 'Come back please !'
    });
  }
});

router.post('/login', passport.authenticate('local'), function(req, res) {
  if ( req.session.passport.user != null ) {
    res.redirect('/');
  } else {
    res.redirect('/register');
  }
});

router.get('/logout', function(req, res) {
  if ( req.session.passport.user != null ) {
    req.logout();
    res.redirect('/');
  }
  else {
    res.redirect('/')
  }
});

module.exports = router;

Я пыталсянекоторые вещи, но в итоге я получил больше ошибок, поэтому я подумал, что будет лучше дать вам оригинальный код.Я не знаю, почему это не работает.Каждый раз, когда я загружаю / регистрирую или / логин это печатает ошибку ниже.
