[firebase-core]: Unable to Initialize Firebase App

先重現 src/app/app.component.ts 中的初始化，並檢查 node_modules/@nativescript/firebase-core/index.android.js 中失敗的 Firebase.initializeApp 路徑，尤其是回報的 FirebaseApp 存取。在追蹤 Android 特有的失敗之前，先檢查專案的 NativeScript 和 Firebase 設定。應用程式能夠成功初始化，且不再出現回報的 undefined FirebaseApp 錯誤，即表示完成。

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
