this error appears in my log. I dont know what can be this is my code: `mport { Component, OnInit } from ‘@angular/core’; import { NavController, Platform } from ‘ionic-angular’;

import { ClientsService } from ‘…/…/providers/clients.service’;

import { GoogleMaps, GoogleMap, GoogleMapsEvent, GoogleMapOptions, CameraPosition, MarkerOptions, Marker } from ‘@ionic-native/google-maps’;

@Component({ selector: ‘page-profile’, templateUrl: ‘profile.html’ }) export class ProfilePage implements OnInit { client: any; map: GoogleMap; mapElement: HTMLElement; constructor(private googleMaps: GoogleMaps, public platform: Platform, public clientsService: ClientsService) {

platform.ready().then(() => {
  this.loadMap1();
});

}

ngOnInit() { this.clientsService.getProfile().subscribe((data: any) => { this.client = data; //this.loadMap1(); }) }

loadMap1() { this.mapElement = document.getElementById(‘map’);

let mapOptions: GoogleMapOptions = {
  camera: {
    target: {
      lat: 43.0741904,
      lng: -89.3809802
    },
    zoom: 18,
    tilt: 30
  }
};

this.map = this.googleMaps.create(this.mapElement, mapOptions);

// Wait the MAP_READY before using any methods.
this.map.one(GoogleMapsEvent.MAP_READY)
  .then(() => {
    console.log('Map is ready!');

    // Now you can use all methods safely.
    this.map.addMarker({
        title: 'Ionic',
        icon: 'blue',
        animation: 'DROP',
        position: {
          lat: 43.0741904,
          lng: -89.3809802
        }
      })
      .then(marker => {
        marker.on(GoogleMapsEvent.MARKER_CLICK)
          .subscribe(() => {
            alert('clicked');
          });
      });

  });

}
