Kiedy próbowałem popchnąć moją aplikację nodejs do herokugit push heroku master, mam to:

error: failed to push some refs to '[email protected]:hidden-reaches-9268.git'

A to mój pakiet.json:

{
  "name": "fnBoard",
  "version": "0.0.1",
  "private": true,
  "scripts": {
  "start": "node server.js"
},

  "dependencies": {
   "socket.io": "0.9.x"
},
   "engines": {
     "node": "0.10.x",
     "npm": "1.3.x"
   }
}

W środku jest kilka błędów i nie mam pojęcia, dlaczego tak się dzieje. proszę pomóż. -dzięki
