I'm trying to make simple sign-in function for my web using firebase however I'm getting an error saying: ERROR db._checkNotDeleted is not a function

my Firebase versions is 9 and React is running on 17.0.2.

This is my firebase config file snippet (Will hide configurations since its unnecessary):

import { initializeApp } from "firebase/app";
import { getAuth, signInWithPopup, GoogleAuthProvider } from "firebase/auth";
import { getDatabase, ref, set } from "firebase/database";
import { getFirestore, doc, getDoc, collection, addDoc, getDocs, query, where} from "firebase/firestore";



const firebaseConfig = {
  */*/*/*/
};

const app = initializeApp(firebaseConfig);


export const auth = getAuth(app);

  export const createUserProfileDocument = async (userAuth, additionalData) => {
    if(!userAuth) return;

    const docRef = doc(db, "users", `${userAuth.uid}`);
    
    const docSnap = await getDoc(docRef);

    if (!docSnap.exists()) {
      const { displayName, email } = userAuth;
      const createdAt = new Date();
    
     
      try {
        await set(ref(db, 'users/' + `${userAuth.uid}`), {
          displayName: "TEST"
        })
        console.log("HERE");
       
      } catch (error) {
        console.log("ERROR", error.message);
      }
    }
    return docRef;
  }

  
  

  const provider = new GoogleAuthProvider();

  export const signInWithGoogle = () => {
      signInWithPopup(auth, provider)
      .then((result) => {
            console.log(result);
      }).catch((error) => {
          console.log(error);
      })
  }
 
  
  
  const db = getFirestore();

Here is my project: https://github.com/poolpy111/oto-clothing/tree/master/src

In debugger error line appears on line 43 which is where I use firebase's "ref" method. What I'm supposed to do?

Firebase has two databases namely Firebase Realtime Database and Cloud Firestore. In the provided code you are creating a DocumentReference by using doc() but then using set() imported from Realtime Database SDK which is causing the error.

If you want to add data in Firestore then import setDoc() from Firestore and refactor the code as shown below:

import { initializeApp } from "firebase/app";
import { getAuth, signInWithPopup, GoogleAuthProvider } from "firebase/auth";
import { getFirestore, doc, getDoc, setDoc, collection, addDoc, getDocs, query, where} from "firebase/firestore";

export const createUserProfileDocument = async (userAuth, additionalData) => {
  if(!userAuth) return;

  const docRef = doc(db, "users", `${userAuth.uid}`);
    
  const docSnap = await getDoc(docRef);

  if (!docSnap.exists()) {
    const { displayName, email } = userAuth;
    const createdAt = new Date();  
     
    try {
      // use setDoc()
      await setDoc(docRef, {
        displayName: "TEST"
      })
      console.log("HERE");   
    } catch (error) {
      console.log("ERROR", error.message);
    }
  }
  return docRef;
}

Follow Firestore's documentation for more information.
