React-native-firebase: 🔥Possible unhandled promise rejection

[selyon]

Issue

I have a listener on a collection like this:
this.unsubscribe = firebase .firestore() .collection(path/to/collection) .where('field', '==', value) .orderBy('field') .onSnapshot(this.snapshotHandler, this.errorHandler);

When the device is offline snapshotHandler and errorHandler are not called, but i get this warning:
Possible Unhandled Promise Rejection (id: 0):
Error: Firestore: The service is currently unavailable. (firestore/unavailable).

How can i catch this type of errors? (offline device or similar)

Do you think that puting your code in a try catch block could solve the problem ?
this.errorHandler is only for listen error on the snapshot method.
