" npm ERR! missing script: start" at Heroku despite set up in package.json and Procfile

Question

I´ve been googling around to try and solve this problem. I´ve modified package.json to look like this:

{
  "name": "webrtc-chat",
  "version": "1.0.0",
  "description": "Simple chat app using WebRTC",
  "main": "index.html",
  "scripts": {
   "start": "node server/server.js", 
   "test": "echo \"Error: no test specified\" && exit 1"
      },
  "author": "Sher Minn Chong",
  "license": "ISC",
  "devDependencies": {
    "grunt": "^0.4.5",
     "grunt-contrib-watch": "^0.6.1",
     "grunt-serve": "^0.1.6",
     "node-static": "^0.7.7"
  },
  "dependencies": {
   "node-static": "^0.7.7",
    "socket.io": "^1.3.6"
  }

}

And Procfile:

web: node server/server.js

Indeed I have server.js in the folder under the root server. I tried with git push -f heroku master when I´d updated the script, then used to destroy to completely wipe the project in case git push wasn´t enough, followed by create but problem persisted.

This is the error log:

Any ideas?

Thanks!

i assume this is related to javascript and not java?

Thanks, I actually went on with another script to tweak and got it working so no need anymore. I will give you the honour though, since it looks like being the solution.
