I see you've deployed a version of the app on our quick hosting server and defined serverURL in your native app to point there.
I think the problem lies in the fact the quick hosting server was using a slightly older version of the platform (2.1.7), while your native app was probably created and tested locally using the stable version (220.127.116.11).
I've update the quick hosting to the same version, and am no longer able to recreate the exception. Note that to be on the safe side, I recommend you redeploy your app on the quick hosting server as well as reinstall the native app on the device (after removing it manually).
