Hi,
This is a known issue in ME 2014. There was a format change in the provision files right before is was released. Of course the simplest solution is to port the HTML5 project to a PhoneGap project and build in ME 2015 as per this tutorial:

As you stated you need to use ME 2014, I will see if we can find someway around this issue but Im not sure if it will be possible. If not, is there something we can help with to get you where you can use ME 2015? Maybe a workaround for a needed feature to something?
If possible can you get me a screen shot of the error as well?
Thanks
