I installed version 9 of FireBase on React 18, I did all the settings correctly, but I do not know why I can not solve the problem no matter what I do, can you help me?

import { initializeApp } from "firebase/app";
import { getFirestore } from "firebase/firestore";


const firebaseConfig = {
    apiKey: x,
    authDomain: x,
    projectId: x,
    storageBucket: x,
    messagingSenderId: x,
    appId: x
};

const app = initializeApp(firebaseConfig);
const db = getFirestore(app);
export { db };
