   6 The Push Messaging server responds with HTTP status code 500
   7 (internal server error) if the app that calls the pushMessaging API
   8 is not found in the Chrome Web Store. This ownership check
   9 is designed to prevent people from sending messages to your app
  10 without your permission. Commonly this error occurs during
  11 development if you run a version of your app without the correct
  12 <code>key</code> attribute in its manifest file.

  16 To fix this problem, simply install your app from
  17 the Chrome Web Store and copy the <a href="manifest/key.html">key</a>
  18 field from manifest.json in the installed app to manifest.json in
  19 the version of the app that you are developing
  20 (see <a href="cloudMessaging.html#test-cloud">Testing in the cloud</a> for
  21 detailed instructions). Note that you need to remove the <code>key</code>
  22 field from manifest.json before you upload the app to the Chrome Web Store again.
