react native expo firebase auth

Question

IM trying to signup an email auth using firebase and Expo but it says an error [2023-06-27T23:36:31.891Z] @firebase/app: Firebase: Error thrown when reading from IndexedDB. Original error: (0 , _idb.openDB) is not a function. (app/idb-get). here is code

const handleSignUp = () => {
  createUserWithEmailAndPassword(auth, email, password)
    .then((userCredential) => {
      // Signed in 
      const user = userCredential.user;
      // ...
    })
    .catch((error) => {
      const errorCode = error.code;
      const errorMessage = error.message;
      // ..
    });}

there is a redd line under auth says Argument of type '{ auth: Auth; app: FirebaseApp; }' is not assignable to parameter of type 'Auth'. Type '{ auth: Auth; app: FirebaseApp; }' is missing the following properties from type 'Auth': name, config, setPersistence, languageCode, and 10 more here is my firebase.js

import { initializeApp } from 'firebase/app';
import { getAnalytics } from "firebase/analytics";
import { getAuth } from "firebase/auth";

// Your web app's Firebase configuration
// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
  **
};


// Initialize Firebase
const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
const analytics = getAnalytics(app);
export default { auth ,app};

re-installing packages

Does that help?

You are probably making a "bad import". In firebase.js you are doing

export default { auth ,app};

and the error says

Argument of type '{ auth: Auth; app: FirebaseApp; }

So the auth you are giving to createUserWithEmailAndPassword is not an "auth object" but an object with keys "auth" and "app".

To fix the problem, I recommend you to delete the

export default { auth ,app}; line

and export things singularly:

export const auth = getAuth(app);

this way auth will be just auth.
