Intento leer algunos datos agregados manualmente en una base de datos de firestore, obtuve el código de este tutorial El código:

 import { initializeApp } from "firebase/app"; import { getAuth, connectAuthEmulator } from "firebase/auth"; import { getFirestore, collection, connectFirestoreEmulator, getDocs } from "firebase/firestore"; const firebaseConfig = { apiKey: process.env.REACT_APP_FIREBASE_API_KEY, authDomain: process.env.REACT_APP_FIREBASE_AUTH_DOMAIN, databaseURL: process.env.REACT_APP_FIREBASE_DATABASE_URL, projectId: process.env.REACT_APP_FIREBASE_PROJECT_ID, storageBucket: process.env.REACT_APP_FIREBASE_STORAGE_BUCKET, messagingSenderId: process.env.REACT_APP_FIREBASE_MESSAGING_SENDER_ID, appId: process.env.REACT_APP_FIREBASE_APP_ID }; const app = initializeApp(firebaseConfig); export const auth = getAuth(app); export const db = getFirestore(app); if(window.location.hostname === "localhost") { connectAuthEmulator(auth, "http://localhost:9099"); connectFirestoreEmulator(db, "http://localhost:8080"); console.log("it's local place"); } const colRef = collection(db, "jobs"); getDocs(colRef) .then((snapshot) => { console.log(snapshot); })

el error que me sale:

 @firebase/firestore: Firestore (9.6.11): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds. This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.
