Sample code not working for my project

Hello, I used the sample code provided in the readme with no success. Perhaps my project needs some adjusting, but I do not know how to debug what’s wrong since no errors are given.

Here is my Express server code:

const express = require('express');
var sslRedirect = require('heroku-ssl-redirect');
const path = require('path');
const favicon = require('serve-favicon');
const logger = require('morgan');
const cookieParser = require('cookie-parser');
const bodyParser = require('body-parser');
const exphbs  = require('express-handlebars');
const app = express();

const routes = require('./routes/index');
const users = require('./routes/user');
const sensor = require('./routes/sensor');

const db = require('./models');

const env = process.env.NODE_ENV || 'development';
app.locals.ENV = env;
app.locals.ENV_DEVELOPMENT = env == 'development';

// view engine setup

app.engine('handlebars', exphbs({
  defaultLayout: 'main',
  partialsDir: ['views/partials/']
}));
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'handlebars');

// app.use(favicon(__dirname + '/public/img/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended: true
}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

// enable ssl redirect
app.use(sslRedirect());

app.use('/', routes);
app.use('/users', users);
app.use('/sensor', sensor);

/// catch 404 and forward to error handler
app.use((req, res, next) => {
  const err = new Error('Not Found');
  err.status = 404;
  next(err);
});

/// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use((err, req, res, next) => {
    res.status(err.status || 500);
    res.render('error', {
      message: err.message,
      error: err,
      title: 'error'
    });
  });
}

// production error handler
// no stacktraces leaked to user
app.use((err, req, res, next) => {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: {},
    title: 'error'
  });
});

app.set('port', process.env.PORT || 3000);

db.sequelize.sync().then(function() {
  let server = app.listen(app.get('port'), function() {
    console.log('Express server listening on port ' + server.address().port);
  });

  // socketIO integration
  let io = require('socket.io').listen(server);

  // listen for a connection request from any client
  io.on('connection', function(socket){
    console.log('a user connected');

    socket.on('disconnect', function () {
      console.log('user disconnected');
    });

    socket.on('p', function(value){
      console.log("pressure: " + value.p);
      io.emit('pc', value);
    });

    socket.on('renewSocketConnection', function(value){
      // console.log("value received from sensor is " + value.pressure);
    });
  });

  exports.server = server;
  exports.io = io;

});

module.exports = app;

Any suggestion on what might be not working? Thanks!

Try move

// enable ssl redirect app.use(sslRedirect());

Before

// view engine setup
