Answer 1

In the firebase console (Overview) Under Your mobile apps click the overflow button (three vertical dots) and goto Manage.

Once there goto your app and download the google-services.json

Add that to the root directory of your app and also to the /app folder.

This worked for me to fix this exact error. I assume I changed something at some point and needed a new one.

Hopefully this helps. Goodluck
