missing script: start & App crashed when deploying app to Heroku

I'm new to coding but currently learning as i want to create a chatbot to my facebook page. Belows are the script i have inside each .js and errors that i came across after that. After i input heroku open, the web shows "Application error An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details."

Hope someone can help me out, a lot of thanks!

index.js

var express = require('express')
var bodyParser = require('body-parser')
var request = require('request')
var app = express()

app.set('port', (process.env.PORT || 5000))

// Process application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({extended: false}))

// Process application/json
app.use(bodyParser.json())

// Index route
app.get('/', function (req, res) {
    res.send('Hello world, I am a chat bot')
})

// for Facebook verification
app.get('/webhook/', function (req, res) {
    if (req.query['hub.verify_token'] === 'my_voice_is_my_password_verify_me') {
        res.send(req.query['hub.challenge'])
    }
    res.send('Error, wrong token')
})

// Spin up the server
app.listen(app.get('port'), function() {
    console.log('running on port', app.get('port'))
})

I have tried and read through quite a lot of questions others have been asking on github, but i still cannot fix the problem. I learnt the method in setting up the nodejs and heroku server from the following website: https://chatbotsmagazine.com/have-15-minutes-create-your-own-facebook-messenger-bot-481a7db54892

I sincerely hope someone can help me out with the problems, thank you so much!!

Solution

  • The Procfile file name should be just Procfile, and I see that yours seems to be named Procfile.json, could be it.

    But as you package.json has the start script, just make sure you have git added all your files and committed them before pushing to Heroku
