FCMPlugin.js: is created FCMPlugin.js:76 FCMPlugin Ready ERROR

I’m having problems with the FCM Plugins, I got this error when call my initializeApp with this code

  private initializeApp(): void {
    if (this.platform.is('android') || this.platform.is('ios')) {
      this.statusBar.styleDefault();
      this.splashScreen.hide();
      this.fcm.getToken().then(token => {
        console.log("TCL: AppComponent -> token", token)
      });
    }
  }

In console I’m having this error

And this is my app.module

import { firebaseConfig } from './../environments/environment';
