Steps to reproduce:

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

I'm not sure if my assumptions are correct, but the error I am encountering comes from calling QueryDocumentSnapshot.data() for a document reference w/c has a GeoPoint(0, 0) value. I have confirmed that @google-cloud/firestore library allows creating this kind of GeoPoint

Relevant Code:

Just create a document with a field location: new admin.firestore.GeoPoint(0,0).

then fetch that document. you will get this error when you call snapshot.data() function in the then() function
