Error: DEVELOPER_ERROR when trying to use GoogleSignIn in React Native

I've enabled the Google SignIn on Firebase and I also added the SHA-1 key. My App compiles fine but when I press the Login button and select a Google account for logging in I get the Possible Unhandled Promise Rejection (id: 0): Error: DEVELOPER_ERROR
When I tried using the anonymous sign in I didn't get any errors. I'm on Android and I have the latest versions for all modules. Here is the full error code:

This is my App.js:

import React, {useState, useEffect} from 'react';
import {View, Text, Button} from 'react-native';

import auth from '@react-native-firebase/auth';
import firebase from '@react-native-firebase/app';
import {GoogleSignin} from '@react-native-community/google-signin';

const firebaseConfig = {
  apiKey: 'xxxx',
  appId: 'xxxx',
  databaseURL: 'https://xxxx.firebaseio.com',
  messagingSenderId: 'xxxx',
  projectId: 'xxxx',
  storageBucket: 'xxxx.appspot.com',
};

if (!firebase.apps.length) {
  firebase.initializeApp(firebaseConfig);
}

const App = () => {
  useEffect(() => {
    // initialize the Google SDK
    GoogleSignin.configure({
      scopes: ['email'],
      webClientId:
        'xxxx.apps.googleusercontent.com',
      offlineAccess: true,
    });
  }, []);

  const googleLogin = async () => {
    // Get the users ID token

    const {idToken} = await GoogleSignin.signIn();
    // Create a Google credential with the token
    const googleCredential = auth.GoogleAuthProvider.credential(idToken);

    // Sign-in the user with the credential
    return auth().signInWithCredential(googleCredential);
  };

  return (
    <View>
      <Button title="Login" onPress={() => googleLogin()}></Button>
    </View>
  );
};

export default App;
