I am newbie. I am following Tutorial from https://www.sitepoint.com/building-facebook-chat-bot-node-heroku/ to make sample facebook messenger bot.

Just when I deployed it first time in heroku I got error

Here is my package.json

{
  "name": "spbot",
  "version": "1.0.0",
  "description": "Testbot",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node app.js"
  },
  "author": "Munkh",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.17.1",
    "express": "^4.15.2",
    "mongoose": "^4.9.1",
    "request": "^2.81.0"
  }
}

here is app.js

    var express = require("express");
var request = require("request");
var bodyParser = require("body-parser");

var app = express();
app.use(bodyParser.urlencoded({extended: false}));
app.use(bodyParser.json());
app.listen((process.env.PORT || 5000));

// Server index page
app.get("/", function (req, res) {
  res.send("Deployed!");
});

// Facebook Webhook
// Used for verification
app.get("/webhook", function (req, res) {
  if (req.query["hub.verify_token"] === "this_is_my_token") {
    console.log("Verified webhook");
    res.status(200).send(req.query["hub.challenge"]);
  } else {
    console.error("Verification failed. The tokens do not match.");
    res.sendStatus(403);
  }
});

I got error like this

Because error doesn't specify what went wrong and just keep crashing, I can't find a solution. My apologies if it is simple question.

You have to specify the node.js and npm version which you are using in package.json, as mentioned below.

Specify the versions which you are using in your development.

{
  "name": "spbot",
  "version": "1.0.0",
  "description": "Testbot",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node app.js"
  },
  "author": "Munkh",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.17.1",
    "express": "^4.15.2",
    "mongoose": "^4.9.1",
    "request": "^2.81.0"
  },
  "engines": {
    "node": "7.0.0",
    "npm": "3.10.8"
  }
}
