What's the solution for fixing the FirebaseError that says 'Firebase: Need to provide options'?

I need assistance with resolving a Firebase error that's occurring in my React-Native application. Can you please provide guidance on how to go about fixing this issue?
The following FirebaseError is occurring: Firebase: Need to provide options, when not being deployed to hosting via source. (app/no-options). Additionally, the error is associated with the JS engine: hermes.

Here is the code for App.js: ```html 
//App.js
import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import LoginScreen from './screens/LoginScreen';
import HomeScreen from './screens/HomeScreen';
import { createNativeStackNavigator } from '@react-navigation/native-stack';


const Stack = createNativeStackNavigator ();

export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        <Stack.Screen  options= {{headerShown:false}} name="LoginScreen" component={LoginScreen}/>
        <Stack.Screen  options={{headerShown:false}} name="HomeScreen" component={HomeScreen}/>
      </Stack.Navigator>
    </NavigationContainer>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});
In addition, this is the Firebase.js code: Firebase.js

// Import the functions you need from the SDKs you need

import {initializeApp} from 'firebase/app';
import {getFirestore} from 'firebase/firestore';
import {getAuth} from 'firebase/auth';

// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries

// Your web app's Firebase configuration
const firebaseConfig = {
  apiKey: "AI***",
  authDomain: "eshopmobile-fb508.firebaseapp.com",
  projectId: "eshopmobile-fb508",
  storageBucket: "eshopmobile-fb508.appspot.com",
  messagingSenderId: "734223583165",
  appId: "1:734223583165:web:6849ecf86323894686b4d4"
};



  // initialize firebase
firebase.initializeApp(firebaseConfig, "eshopmobile");
console.log(app);

const db = getFirestore(app);
const auth = getAuth(app);

The error message you are seeing is related to Firebase initialization options. According to the Firebase documentation, if you initialize your app without a valid set of Firebase options, new users of your application will experience serious issues. To fix this issue, you need to provide options when initializing Firebase. You can do this by passing an object with the required options as an argument to the initializeApp() function. Here is an example of how you can modify your Firebase.js code to include the required options: 
<pre><code>// Import the functions you need from the SDKs you need

import {initializeApp} from 'firebase/app';
import {getFirestore} from 'firebase/firestore';
import {getAuth} from 'firebase/auth';

// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries

// Your web app's Firebase configuration
const firebaseConfig = {
  apiKey: "AI***",
  authDomain: "eshopmobile-fb508.firebaseapp.com",
  projectId: "eshopmobile-fb508",
  storageBucket: "eshopmobile-fb508.appspot.com",
  messagingSenderId: "734223583165",
  appId: "1:734223583165:web:6849ecf86323894686b4d4"
};

// initialize firebase
const app = initializeApp(firebaseConfig); // add options here
console.log(app);

const db = getFirestore(app);
const auth = getAuth(app);
</code></pre>

I hope this helps! Let me know if you have any other questio

The error message you are receiving suggests that you need to provide options when initializing firebase through Firebase SDK. You should either provide the Firebase configuration options directly as a parameter to firebase.initializeApp() or specify them as an object when calling getFirestore() and getAuth() functions. Here's how you can fix the issue: 
//Firebase.js
// Import the functions you need from the SDKs you need
import { initializeApp } from 'firebase/app';
import { getFirestore } from 'firebase/firestore';
import { getAuth } from 'firebase/auth';

// Your web app's Firebase configuration
const firebaseConfig = {
  apiKey: "AI***",
  authDomain: "eshopmobile-fb508.firebaseapp.com",
  projectId: "eshopmobile-fb508",
  storageBucket: "eshopmobile-fb508.appspot.com",
  messagingSenderId: "734223583165",
  appId: "1:734223583165:web:6849ecf86323894686b4d4"
};

// initialize firebase with options
const app = initializeApp(firebaseConfig);

const db = getFirestore(app);
const auth = getAuth(app);

export { db, auth };
In the code above, the Firebase configuration options are directly passed as a parameter to initializeApp(). This should solve your issue.
