Пример HackHands Satellizer - неожиданная проблема с токеном

Я использую этот пример HackHands, чтобы начать работу с Satellizer и застрял на запуске экспресс server- https://hackhands.com/building-instagram-clone-angularjs-satellizer-nodejs-mongodb/

Вот мой сервер. js-

var bcrypt = require('bcryptjs');
var bodyParser = require('body-parser');
var cors = require('cors');
var express = require('express');
var jwt = require('jwt-simple');
var moment = require('moment');
var mongoose = require('mongoose');
var path = require('path');
var request = require('request');

var config = require('./config');

var User = mongoose.model('User', new mongoose.Schema({

   instagramId: { type: String, index: true },
   email: { type: String, unique: true, lowercase: true },
   password: { type: String, select: false },
   username: String,
   fullname: String,
   picture: String,
  accesstoken: String
 }));
mongoose.connect(config.db);

var app = express();

app.set('port', process.env.PORT || 3000);
app.use(cors());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));

function createToken(user){
  var payload = {
   exp: moment().add(14, 'days').unix(),
    iat: moment().unix(),
    sub: user._id

  return jwt.encode(payload, config.tokenSecret);
}


function isAuthenticated(req, res, next) {
  if (!(req.headers && req.headers.authorization)) {
return res.status(400).send({ message: 'You did not provide a JSON Web Token in the Authorization header.' });
  }

  var token = header[1];

Я всегда получаю эту ошибку в terminal- SyntaxError: Неожиданный токен; на export.runInThisContext(vm.js: 73: 16) в Module._compile (module.js: 443: 25) в Object.Module._extensions..js(module.js: 478: 10) на Module.load (модуль.js: 355: 32) в Function.Module._load (module.js: 310: 12) в Function.Module.runMain(module.js: 501:10) при запуске (node.js: 129: 16) на узле.js: 814: 3

Не уверен, что мне здесь не хватает. Может ли кто-нибудь помочь?

Мой пакет.json вставлен below-

{

"name": "instagram-server", "version": "0.0.0", "scripts": {"start": "node server.js"}, "dependencies": {"bcryptjs": "^ 2.0. 2 "," body-parser ":" ^ 1.8.1 "," cors ":" ^ 2.4.2 "," express ":" ^ 4.9.0 "," jwt-simple ":" ^ 0.2.0 ", "момент": "^ 2.8.3", "мангуста": "^ 3.8.17", "запрос": "^ 2.44.0"}
