Heroku deployment fails with "missing script: start"

Question

I am trying to upload my local MEAN stack based web application to my Heroku server. I have updated my code in Bitbucket and have successfully done the Heroku deployment part. But, the web app is still not live. When I hit the page, I am getting something like this:

I then checked the logs by firing 'heroku logs' but I am unable to understand what the logs are trying to ask for. I am sharing the logs below:

As I understand it, the application was unable to find "start" but I have later exclusively added "start" : "node app.js" but I still don't see any difference in the heroku logs or in the heroku link.

Can anyone help with what am I doing wrong here?

here's my package.json file

{
  "start": "node app.js",
  "name": "PerosnalPro",
  "version": "1.0.0",
  "description": "Personal website using dynamic routing and responsive design.",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Mikey",
  "license": "ISC",
  "dependencies": {
    "dotenv": "^1.2.0",
    "ejs": "^2.3.4",
    "express": "^4.13.3",
    "morgan": "^1.6.1",
    "serve-favicon": "^2.3.0",
    "slick-carousel": "^1.5.9"
  },
  "devDependencies": {},
  "repository": {
    "type": "git",
    "url": "git+https://[email protected]/username/projectname"
  },
  "homepage": "https://bitbucket.org/username/projectname"
}

Just to clarify, you added the missing start like this AND you pushed the change to heroku? — Gino Mempin

"scripts": {
     "start" : "node app.js", 
     "test": "echo \"Error: no test specified                   \" && exit 1"
 }

Add your start tag in scripts. :)
