tracing error response on HttpInterceptor

In my angular 6 application I am receiving error message from API, below is the code.

intercept(req: HttpRequest<any>, next: HttpHandler):Observable<HttpEvent<any>>{
 return next.handle(req)
 .pipe(
  catchError((error: HttpErrorResponse)=>{
   // const err="error occured"; 
   // console.log(error);
   // console.log(error.error.['@errors'].code);
   // console.log(`error log`, error.error.code)
    if (error.error['@errors'].code != 'ERR_UNITLIMIT') {
    this.MyService.errorHasOccurred(err);}
    return throwError(error);
   })
 );
 }

I am getting below response from service like below

{"@errors":[{"code":"ERR_UNITLIMIT","message":"total cart value must not be exceed 500$.","details":[]}],"@warnings":[]}

I am trying to check if response object code contains ERR_UNITLIMIT or not . I tried things which has been commented in above code using // but always getting error of code is undefined.

Since "@errors" is an array of objects , you have to refer it using the index 0. console.log(error.error['@errors'][0].code) will do the job.

change your function as below

intercept(req: HttpRequest<any>, next: HttpHandler):Observable<HttpEvent<any>>{
 return next.handle(req)
 .pipe(
  catchError((error: HttpErrorResponse)=>{
    if (error.error['@errors'][0].code != 'ERR_UNITLIMIT') {
    this.MyService.errorHasOccurred(error);}
    return throwError(error);
   })
 );
 }
