title: How to debug chrome manifest.json?
body: <p>I am working on a chrome.bluetooth app. However, there's something wrong with the manifest.json. However, I don't see any way to set a breakpoint in the manifest.json - obviously, it's declarative.</p>
  
  <p>My manifest.json is:</p>
  
  <pre><code>{
    "name": "Bluetooth Low Energy Test App",
    "description": "App testing the chrome.bluetoothLowEnergy API",
    "version": "0.1",
    "app": {
      "background": {
        "scripts": ["background.js"]
      }
    },
    "bluetooth": {
      "low_energy": true
    }
  }
  </code></pre>
  
  <p>Is there a way to debug manifest.json? That is, to see how or where it may be providing the wrong values for it's various declarations. A linter? Anything?</p>
  
  <p>I've tried this on stable (42) and canary (44) builds of chrome on Mac OSX and ChromeOS and don't see an obvious solution.</p>
