title: Chrome app "Bad client id: UNSUPPORTED"
body: <p>I have a client Id set in my manifest file that matches the one I created in the google api console.</p>
  
  <p>I created it as an application client ID.</p>
  
  <p>Manifest.json:</p>
  
  <pre><code>"oauth2": {
      "client_id": "mysecretclientID",
      "scopes": [
        "https://www.googleapis.com/auth/drive"
      ]
  }
  </code></pre>
  
  <p>I'm testing this in the dev console for my chrome app with this code:</p>
  
  <pre><code>chrome.identity.getAuthToken({interactive: false}, function(token){console.log(token);})
  </code></pre>
  
  <p>What does this error mean? </p>
