[ionic-native 3.4.2] TypeError: plugin.constructor.getPluginRef is not a function

[azakusilo]

Hello I wrote a wrapper for ionic native push plugin. But after the App is starts. It's get a error TypeError: plugin.constructor.getPluginRef is not a function.
Here is a code of my wrapper:

import { Injectable } from "@angular/core";
import {
  Push, PushObject, PushOptions, EventResponse, NotificationEventResponse,
  RegistrationEventResponse
} from '@ionic-native/push';
import { Events, ToastController, Platform, App, NavController } from "ionic-angular";
import { Device } from "ionic-native";
import { APP_CONFIG } from "../app/app.config";
/**
 * Класс сервиса для управления PUSH уведомлениями
 */
@Injectable()
export class PushNotificationService {
  register_token_url = '/api/methods/push.registerToken';
  pushNotification: PushObject; //Notification's API
  push_token = "";
  messages_stack_id = []; //Messages stack


  /**
   * Constructor of class
   *
   */
  constructor(
    public plt: Platform,
    public toastCtrl: ToastController,
    public appCtrl: App,
    public httpRequestService: HttpRequestService,
    public authService: AuthService,
    public events: Events,
    public push: Push
  ){

  }

  /**
   * Initialization
   */
  init()
  {
     let pushSenderID = APP_CONFIG.pushSenderID.toString();
     if (pushSenderID.length) { //If we have sender id

       const options: PushOptions = {
         android: {
           sound: true,
           vibrate: true,
           forceShow: false,
           senderID: pushSenderID
         },
         ios: {
           alert: true,
           badge: true,
           sound: true,
           gcmSandbox: true,
           senderID: pushSenderID
         },
         windows: {}
       };

       this.pushNotification = this.push.init(options);

       //Check the rights
       if (this.plt.is('ios') || this.plt.is('android')) {
         this.pushNotification.hasPermission().then((isEnabled) => { //If we get push rights
           if (!isEnabled){
             this.showToast('No right to get push notify.');
           }else{
             console.log('We have PUSH permission!');
           }
         }).catch((reason) => {
           this.showToast('No right to get push notify: ' + reason.toString()); //Here is a error
         });
       }

       //Registration of token
       this.pushNotification.on('registration').subscribe((data: RegistrationEventResponse) => {
         this.onRegistrationToken(data);
       });

       //Get Notification
       this.pushNotification.on('notification').subscribe((data: NotificationEventResponse) => {
         this.onNotification(data);
       });


       //Get errors
       this.pushNotification.on('error').subscribe((e: Error) => {
         console.error(e.message);
         this.showToast("PUSH Error: " + e.message);
       });
     }
  }
}

I got lastest installed packeges:

    "@ionic-native/core": "^3.4.2",
    "@ionic-native/push": "^3.4.2",

I updated my package but still have the same error in the same place of code on check hasPermission

@azakusilo just updated the push plugin.

hasPermission should be part of the Push class and not PushObject.

Correct usage is:

this.push.hasPermission()
  .then(res => console.log('Has permission?', res.isEnabled);

Update @ionic-native/push to 3.4.4.
