heroku部署失败“应用程序错误”

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

Check your logs. You're using Papertrail.
