Answer 1

This error is caused when the device is unable to register to Firebase. Make sure the internet is working when this code is called. And put the code within try-catch to stop app from crashing.

Edit: Either add an internet connection check before registering the device or fetching token. Or wrap the Fetch token code in try-catch block to prevent app from crashing.

1- Internet connection
