Error while deploying NodeJs app on Heroku

Question

I've tried to deploy my NodeJs app on Heroku, follows all steps on Heroku guide but I can't make it running. Here is the log:

Any thoughts?

[EDIT]

package.json:

"engines": {
  "node": "5.11.1",
  "npm": "3.8.6"
  },
  "scripts": {
    "start": "node app.js"
  },

Procfile:

web: npm start

package.json

{
  "name": "your-project-name",
  "version": "1.0.0",
  "description": "desc",
  "main": "app.js",
  "scripts": {
    "start": "node app.js",
    ...
  }
  ...
}

Procfile

Above package.json is file good to go without a Procfile. Yet, if you want to have one, you can define it as follows:

web: node app.js

You need to tell Heroku how to start your app. Either do that by specifying a "start" script in package.json, or by providing a Procfile.
