I have included the start script like this

"scripts": {
"start": "node server/server.js",
"test": "export NODE_ENV=test || SET \"NODE_ENV=test\" && mocha \"./{,!(node_modules)/**/}*.test.js\""
},

please tell me what i am missing. I have also attached my root directory folders image. image

As soon as you are already using Procfile, you can specify there: web: node server/server.js

By default, Heroku looks into the Profice first in order to start server. And only then it looks into package.json's start script.
