heroku deployment fails "Application error" - node.js

Question

error message on the page
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.
I have saw several questions like mine,
Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)
Heroku code=H10 desc="App crashed" - Can't figure out why it's crashing
but I don't think I made the same mistake.
const express = require('express');
const app = express();
const wetalk = require('./app');
const passport = require('passport');
app.set('port', process.env.PORT || 3000);
app.use(express.static('public'));
app.set('view engine', 'ejs');
app.use(wetalk.session);
app.use(passport.initialize());
app.use(passport.session());
app.use(require('morgan')('combined', {
stream: {
write: message => {
//write to logs
wetalk.logger.log('info', message);
}
}
}));
//router
app.use('/', wetalk.router);
wetalk.ioServer(app).listen(app.get('port'), () => {
console.log('Wetalk running on the port', app.get('port'));
});
Here below is my console on git push heroku master
