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

Can you try installing one of the other firebase packages e.g firebase-analytics

You need to remove @nativescript/firebase
