Issue: FirebaseError: No Firebase App '[DEFAULT]' has been created

[palashshah110]

Description

I am encountering the following error when using the refine-firebase-adapter package in my project:

FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been created - call initializeApp() first (app/no-app)

This error occurs even though I have called the initializeFirebase function before using any Firebase services.

Steps to Reproduce

1. Install the refine-firebase-adapter package.
2. Create a Firebase configuration object.
3. Call the initializeFirebase function with the configuration object.
4. Attempt to use auth and db services.

Example Code

Here is a simplified version of my code:
`import { initializeFirebase } from 'refine-firebase-adapter';

const firebaseConfig = {
apiKey: "apikey",
authDomain: "key",
projectId: "key",
storageBucket: "key",
messagingSenderId: "key",
appId: "key"
};

// Initialize Firebase
const { auth, db } = initializeFirebase(firebaseConfig);

// Attempt to use auth and db
console.log(auth, db);

Expected Behavior

I expect the Firebase app to be initialized, and the auth and db services to be available for use without throwing any errors.

Actual Behavior

The error FirebaseError: No Firebase App '[DEFAULT]' has been created - call initializeApp() first (app/no-app) is thrown, indicating that Firebase is not properly initialized.

Package Code

Here is the relevant part of the refine-firebase-adapter package code:

src/firebase/firebaseconfig.ts:`

`import { initializeApp, FirebaseApp } from 'firebase/app';
import { getAuth, Auth } from 'firebase/auth';
import { getFirestore, Firestore } from 'firebase/firestore';

let app: FirebaseApp | null = null;
let auth: Auth;
let db: Firestore;

const initializeFirebase = (firebaseConfig: any) => {
if (!app) {
app = initializeApp(firebaseConfig);
auth = getAuth(app);
db = getFirestore(app);
}
return { auth, db };
};

export { initializeFirebase, auth, db };
`
src/index.ts:

export { default as authprovider } from './authprovider/authprovider'; export { default as dataprovider } from './dataprovider/dataprovider'; export { initializeFirebase, auth, db } from './firebase/firebaseconfig';

Additional Context

I have ensured that initializeFirebase is called before any Firebase services are used.
The configuration object is correctly provided.
The issue persists even after re-publishing the package and reinstalling dependencies.

Environment

Node version: [e.g., 14.x]
npm version: [e.g., 6.x]
Package version: [e.g., 1.0.0]
Firebase version: [e.g., 9.6.1]
Any guidance or help to resolve this issue would be greatly appreciated. Thank you!
