SyntaxError: Unexpected end of input

[Adnan Salahuddin]

Hi,
I am new angular 2.

Here is i am using Htttp put service.

    this.http.put(window.location.href.split('#')[0] + 'api/vacancy/' + 2, JSON.stringify(updateVacancyValue), { headers: headers }).map(res => res.json()).subscribe(vacancy => this.vacancy = vacancy);

I am getting error message in console (Google Chrome) and it says :

EXCEPTION: SyntaxError: Unexpected end of input

how do i fix it?
I am waiting for your response. Thanks

Hi Adnan!

I think this error might be related with JSON parsing, don't know if JSON.stringify(updateVacancyValue) or res.json().
You could try to console.log both to see if the error is in fact related with JSON parsing.

if I removed map function and parameter in Subscribe then update (http put service) is working

this.http.put(window.location.href.split('#')[0] + 'api/vacancy/' + 2, JSON.stringify(updateVacancyValue), { headers: headers }).subscribe();

I do not understand of any this.
