处理订阅块中的错误而不是 Http 拦截器

Question

I am calling an api through angular service as below

this.someservice.save(this.someID, this.payload).subscribe(
  res => { },
  err => { },
  () =>{} );

As per some business rule i am throwing a custom exception from API but when i put a debugger inside error block, it does not show any info, instead it jump to interceptor and show there that info.

Is there any way that i can receive this info here instead of interceptor inside

err => { debugger; need too get exception here },

Reason for this is that i am returning a custom error specific only for this angular component (from where i am calling this service) so need to handle error on this component but this project is allready configured with an HTTP interceptor which is catching all the error at one place.

You can import from 'rxjs/operators' like this:

import { pipe, catchError } from 'rxjs/operators';

and then you can use it before subscribe like this:

this.someService.save(...args).pipe(catchError( err => console.log(err)).subscribe();
