Are you importing AngularFireDatabaseModule in your CoreModule, for example:

@NgModule({
  imports: [
    CommonModule,
    HttpClientModule,
    IonicModule,
    AngularFireModule.initializeApp(ENV.firebase),
    AngularFireDatabaseModule
    AngularFireAuthModule,
    ...
  ],
  exports: [],
  declarations: [],
  providers: [
    ...
  ]
})
export class CoreModule {
  constructor( @Optional() @SkipSelf() parentModule: CoreModule) {
     ...
  }
}

No, I have imported now and it worked properly . Thank you so much @robinyo :smile:

I ran into this error after trying to set a global variable.

Followed this How to change value of global variable on any files in Ionic?
