Getting error when firebase SignOut on react native - reactjs

Question

All works ok, sign in, signup, even the database, but when I am trying to sign out this error show up:
[TypeError: undefined is not an object (evaluating
'_$$_REQUIRE(_dependencyMap[0],
"#firebase/util").getModularInstance(auth).signOut')]
This is my firebase file:
import { initializeApp, getApps} from 'firebase/app';
import {initializeAuth, getAuth} from 'firebase/auth';
import { initializeFirestore } from 'firebase/firestore';
import { getReactNativePersistence } from 'firebase/auth/react-native';
import AsyncStorage from '#react-native-async-storage/async-storage';
import {REACT_APP_APIKEY,
REACT_APP_AUTHDOMAIN,
REACT_APP_PROJECTID,
REACT_APP_STORAGEBUCKET,
REACT_APP_MESSAGINGSENDERID,
REACT_APP_APPID
} from "#env"
// Firebase config
const firebaseConfig = {
apiKey: REACT_APP_APIKEY,
authDomain: REACT_APP_AUTHDOMAIN,
projectId: REACT_APP_PROJECTID,
storageBucket: REACT_APP_STORAGEBUCKET,
messagingSenderId: REACT_APP_MESSAGINGSENDERID,
appId: REACT_APP_APPID,
};
// initialize firebase
let firebaseApp;
let auth;
if (getApps().length < 1) {
firebaseApp = initializeApp(firebaseConfig);
auth = initializeAuth(firebaseApp, {
persistence: getReactNativePersistence(AsyncStorage),
});
} else {
auth = getAuth();
}
export default auth;
export const database = initializeFirestore(firebaseApp, {
experimentalForceLongPolling: true,
});
This is when I am calling the function:
import { signOut } from 'firebase/auth';
import {database, auth} from '../config/firebase';
const onSignOut = () => {
try {
signOut(auth).then(()=> console.log("signout"))
} catch (error) {
console.log('Error logging out: ', error)
}
};

I finally found the problem, it was my mistake.
As you can see in my firebase file, I export the "auth" as default, but when I am trying to import it, I am importing inside the curly braces {auth}, but It must be outside due it is default. I fixed that and the problem is fixed.
this is the right way:
import auth, {database} from '../config/firebase';
