firebase-tools: PERMISSION_DENIED in firebase emulator using Google Auth provider

[REQUIRED] Environment info

firebase-tools: 9.8.0

Platform: MacOS Catalina 10.15.6

[REQUIRED] Test case

I’m trying to insert data in firebase firestore emulator. I’m using two emulators : firestore and auth. User is logged using Google auth provider. So I created a mock user that have Google as auth provider. But I can’t insert data with firestore auth rules.

// firebase web SDK config
import firebase from "firebase/app";

import "firebase/analytics";
import "firebase/auth";
import "firebase/firestore";
import { isMock } from "../utils/environement";

const firebaseConfig = {
  apiKey: "...",
  authDomain: "...",
  projectId: "...",
  storageBucket: "...",
  messagingSenderId: "...",
  appId: "...",
  measurementId: "...",
};

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

if (isMock) {
  firebase.auth().useEmulator("http://localhost:9099");

  firebase.firestore().settings({
    experimentalForceLongPolling: true,
  });
  firebase.firestore.setLogLevel("debug");
  firebase.firestore().useEmulator("0.0.0.0", 8080);
}

export default firebase;

// firestore.rules

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

// firebase.json
{
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "storage": {
    "rules": "storage.rules"
  },
  "emulators": {
    "auth": {
      "port": 9099
    },
    "firestore": {
      "port": 8080
    },
    "ui": {
      "enabled": true
    }
  }
}

[REQUIRED] Steps to reproduce

My app is a next.js app. So next start and firebase emulators:start.

In my code I try to do the following

const MyComponent = () => {
  React.useEffect(() => {
    firebase.firestore().collection("users").add({ some: "data" })
  }, [])
  
  return (...)
}

[REQUIRED] Expected behavior

I’m expecting to have my data inserted -

[REQUIRED] Actual behavior

An error is sent
