Error on Cordova App

[paranoico]

Hello and thanks for your great work.

We are experiencing some problems trying to implement your package, when testing on Android, the Cordova Application raises the following error:
Failed to register a ServiceWorker: An unknown error occurred when fetching the script

The error does not appear when testing on Chrome, just in Cordova.

I have googled a lot trying to find some reason, but found nothing yet.

Thanks again in advance.
