Angular 4 get call stuck browser and application

Question

In my angular 4 application I have a problem with a standard http get, and in Chrome if I see the header of this call I see: Provisional headers are shown afer that call chrome remains stucked, I need to kill it to make it works again.

If I try to debug I see that the map operator in my service is not executed, and also the subscribe in the component is not executed. This Get make the call with the correct link, and it is not a backend problem,

so why my application/chrome result stucked and I can't see any errors?

Component

  ngOnInit() {
      this.loadNotes(10);
  }



  loadNotes(items: number) {
    this.noteService.getNotes2(this.link, items, this.currentPage)
      .subscribe(response => {
        console.log('subscribe');
        this.ticketBundleNoteList = response._embedded.notes as Note[]; 
      },
      error => {console.log('error')})
}

noteService

 getNotes2(url: string, items, page) {

    let params = new HttpParams().set('size', items);
    params = params.set('page', page);
    console.log('SERVICE NOTE')
      return this.http.get('http://....../api/v1/depositReceipts/search/getNotes?id=1')
        .map((response) => <any>response)
    }

"*I see that the map operator in my service is not executed*". There is no `.map` in the provided code ..? — n00dl3, Oct 20 '17 at 13:30

Are you sure the problem is not somewhere else? Since browser freezes, seems to me it could be something else like an infinite loop or something. Your code works fine without this pieces of code? — AT82, Oct 20 '17 at 14:49
@AJT_82 good point, this component is included in other component and load the notes ` ` — Alessandro Celeghin, Oct 20 '17 at 14:59
in addition to above point, what's going on in your network tab, are there multiple calls? — arbghl, Feb 27 '19 at 11:57
