Error - git push heroku master

Question

If you're attempting to help me, I really appreciate it. So when I write git push heroku master, it fails to parse, and before you spit at me and say 'READ OTHERS!!!!' I have. I've rewritten the package.JSON and used a validator. The strange thing is it always says line 9, column 3, every time I reformat the package.JSON, always line 9, column 3. I have changed over 5-7 times. I don't think my package.json is necessary as it always brings that error. But here it is anyway.

{
  "name": "vulture",
  "version": "1.0.1",
  "description": "Vulture is a bot for discord.",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "engines": {
    "node": "8.4.0",
    "npm": "5.4.0"
  },
  "author": "swagehsaan840#0336",
  "license": "MIT"
}

A side note is changing it will probably give me the same error, but I never know, after using a validator and changing any times, it always says line 9, column 3. Thanks anyway! :)
