Firebase Adapter v4 not working

[eddyhdzg]

I'm following the code example in https://next-auth.js.org/adapters/firebase but I can't make it work.

Any solutions?

My current code.

import NextAuth, { type NextAuthOptions } from "next-auth";
import { FirestoreAdapter } from "@next-auth/firebase-adapter";
import GoogleProvider from "next-auth/providers/google";
import { initializeApp, getApp, getApps } from "firebase/app";
import { getFirestore } from "firebase/firestore";
import { getAuth } from "firebase/auth";

const firebaseConfig = {
  apiKey: process.env.FIREBASE_API_KEY,
  appId: process.env.FIREBASE_APP_ID,
  authDomain: process.env.FIREBASE_AUTH_DOMAIN,
  projectId: process.env.FIREBASE_PROJECT_ID,
  storageBucket: process.env.FIREBASE_STORAGE_BUCKET,
  messagingSenderId: process.env.FIREBASE_MESSAGING_SENDER_ID,
  measurementId: process.env.FIREBASE_MEASUREMENT_ID,
};

export const app = !getApps().length ? initializeApp(firebaseConfig) : getApp();
export const auth = getAuth(app);
export const db = getFirestore(app);

export const authOptions: NextAuthOptions = {
  providers: [
    GoogleProvider({
      clientId: process.env.GOOGLE_ID || "",
      clientSecret: process.env.GOOGLE_SECRET || "",
    }),
  ],
  adapter: FirestoreAdapter(firebaseConfig),
};

export default NextAuth(authOptions);

I just had to add a url on the the Authorized redirect URIs on the GCP console...
