在ANGULAR拦截器中捕获错误消息

Question

我正在尝试在API和客户端中创建集中式错误处理程序，但是角度拦截器从不捕获错误描述模型。拦截器中的错误消息始终为：“ URL的HTTP故障响应：0未知错误”。 API中的错误处理程序始终捕获所有错误和异常。当我使用邮递员时，错误模型会定期显示

app.UseExceptionHandler(errorApp =>
            {
                errorApp.Run(async context =>
                {
                    var errorFeature = context.Features.Get<IExceptionHandlerFeature>();
                    var exception = errorFeature.Error;                    

                    var problemDetails = new ProblemDetails
                    {
                        Instance = $"urn:myorganization:error:{Guid.NewGuid()}"
                    };

                    if (exception is BadHttpRequestException badHttpRequestException)
                    {
                        problemDetails.Title = "Invalid request";
                        problemDetails.Status = (int)typeof(BadHttpRequestException).GetProperty("StatusCode",
                            BindingFlags.NonPublic | BindingFlags.Instance).GetValue(badHttpRequestException);
                        problemDetails.Detail = badHttpRequestException.Message;
                    }
                    else
                    {
                        problemDetails.Title = "An unexpected error occurred!";
                        problemDetails.Status = 500;
                        problemDetails.Detail = exception.Message.ToString(); 
                    }

                    // log the exception etc..

                    context.Response.StatusCode = problemDetails.Status.Value;
                    context.Response.WriteJson(problemDetails, "application/problem+json");
                });
            });

这是角度拦截器：

intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

    return next.handle(request).pipe(
        delay(0),
        map((event: HttpEvent<any>) => {
            this.Loader = true;

            return event;
        }),
        catchError((error: any) => {                
            console.log('error--->>>', error);                
            return throwError(error);
        }),
        finalize(() =>{
            this.Loader = false;
        }));
}

任何人都知道我在做什么错。 谢谢
