The problem was with git add.I had forgotten to add the node_modules files.I closed the terminal and ran the set of commands given in the Getting started with Heroku and NodeJs[1] again.The application was successfully pushed onto the stack.

But I thought you're not supposed to check node_modules into git? NPM should install the dependencies when you run "npm install" ?? – conor909 Sep 25 '15 at 10:48

@conor909: Yes, I should hope that node modules needn't be pushed to heroku too, but if you see the steps here https://devcenter.heroku.com/articles/getting-started-with-nodejs#push-local-changes that's exactly what it says to do. Maybe someone can clarify if the node modules need to be pushed to git and heroku. – Aravind Sep 26 '15 at 17:30
