Make sure you have both the debug and release keys in your Firebase application. If it this error appears in production, add your SHA-1 release key to fire base app. If it appears in development, then add your SHA-1 debug key.

Getting the debug/release key:

keytool -exportcert -list -v -alias [your alias] -keystore [path/to/debug or release.keystore]

Make sure to download the updated google-services.json to your app.
