[firebase-core]: Unable to Initialize Firebase App

Start by reproducing the initialization from src/app/app.component.ts and inspect the failing Firebase.initializeApp path in node_modules/@nativescript/firebase-core/index.android.js, especially the reported FirebaseApp access. Check the project’s NativeScript and Firebase setup before tracing the Android-specific failure. Done means the app initializes successfully without the reported undefined FirebaseApp error.

Hello Team,
Can you assist with the error below, when trying to initialize the firebase app from the firebase-core?
Here is how I am initializing it

export class AppComponent implements OnInit {

    ngOnInit(): void {
        firebase().initializeApp().then((app) => {
            console.log(app);
        })
    }

}

Here is the error that shows up
