I’m currently experiencing this error when sending a message from FCM, and using this module with the latest version of react-native 0.34.1 and this module at 2.1.1

And in my build.gradle:

    compile project(':react-native-push-notification')
    compile ('com.google.android.gms:play-services-gcm:9.4.0') {
       force = true;
    }
    compile('com.google.firebase:firebase-core:9.4.0')
    compile('com.google.firebase:firebase-messaging:9.4.0')

I see this problem occurring as well in other libs: https://github.com/rpush/rpush/issues/292 such as in rpush as of 2 days ago

The error appears to basically be identical. this is just by using the FCM messaging tool in firebase console, sending some test messages.

I also noticed this also https://github.com/morinel/gcmpush/issues/45 , no sure if there is a relationship, but it appears to be the same type and property.

I also found a thread here, that states the property might be added by google play services https://bugs.chromium.org/p/chromium/issues/detail?id=639313

Be careful that there are two package with sensibly the same name…

This one is react-native-push-notification (without S). You are referring to react-native-push-notifications: https://www.npmjs.com/package/react-native-push-notifications I never used this one.

Yes, react-native-push-notifications seems to be a fork of this repo from a long time ago.
