How to handle ajax error?

[Discountrobot]

please elaborate.

Since the rest client is simply returning a RxJS observable, you should read up on how the RxJS/subscribe method works.

You simply supply another callback like so:

  myMethod
  .subscribe(
    data => console.log(data),
    err => console.log(err),
    () => console.log('Completed')
  );

add responseInterceptor. after use like this return response.catch (()=>{});
