Angular 2 and FireBase messagning - unable to register

I am developing Angular 2 web app and want to register Firebase Messaging and obtain token.

I am using angularfire2 for Angular 2. I use Angular ng serve local development environment. Unfortunatelly the browser console shows me below errors:

V browserErrorMessage : "Failed to register a ServiceWorker: A bad HTTP response code (404) was received when fetching the script." code : "messaging/failed-serviceworker-registration" message : "Messaging: We are unable to register the default service worker.

Below is the code of my service.

import { Inject, Injectable } from "@angular/core";
import { FirebaseApp } from "angularfire2";
import * as firebase from 'firebase';

@Injectable()
export class FirebaseMessagingService {

  private messaging: firebase.messaging.Messaging;

  constructor( @Inject(FirebaseApp) private firebaseApp: firebase.app.App) {
    console.log("FirebaseMessagingService init...");
    this.messaging = firebase.messaging(this.firebaseApp);
    
  }


  init() {

    

    this.messaging.requestPermission()
      .then(() => {
        this.onFirebaseInitialized();
      })
      .catch((error) => {
        console.log("FirebaseMessagingService requestPermission error:" + error);

      });
  }

  private onFirebaseInitialized() {
    console.log("FirebaseMessagingService initialized");

    /*this.messaging.setBackgroundMessageHandler(message => {
      
    })*/

    this.getToken();


    // Callback fired if Instance ID token is updated.
    this.messaging.onTokenRefresh(() => {
      this.getToken();
    });

    

    this.messaging.onMessage((payload) => {
      console.log("Message received. ", payload);
      // ...
    });
    


  }

  getToken() {
    this.messaging.getToken()
      .then((currentToken) => {
        console.log('getToken() received');
        if (currentToken) {
          this.sendTokenToServer(currentToken);
          this.updateUIForPushEnabled(currentToken);
        } else {
          // Show permission request.
          console.log('No Instance ID token available. Request permission to generate one.');
          // Show permission UI.
          this.updateUIForPushPermissionRequired();
          this.setTokenSentToServer(false);
        }
      })
      .catch(function (err) {
        console.log('An error occurred while retrieving token. ', err);
        //this.showToken('Error retrieving Instance ID token. ', err);
        //this.setTokenSentToServer(false);
      });
  }


  sendTokenToServer(token) {

  }

  updateUIForPushEnabled(token) {

  }

  updateUIForPushPermissionRequired() {

  }

  setTokenSentToServer(isSent: boolean) {

  }
