NancyFx没有到达pipelines.OnError

Question

我在这样的路线中检查身份验证：

private dynamic GetAll()
{
    this.RequiresAuthentication();
    var data = _tourRepository.GetAll();
    return Response.AsJson(data);
}

如果用户未经过身份验证，则RequiresAuthentication()会抛出错误 导致我进入管道的错误：

protected override void ApplicationStartup(TinyIoCContainer container, IPipelines pipelines)
{
    StaticConfiguration.DisableErrorTraces = false;
    pipelines.OnError += (ctx, ex) =>
    {
        if (ex is RouteExecutionEarlyExitException)
            return ((RouteExecutionEarlyExitException)ex).Response;

        return new Response { StatusCode = HttpStatusCode.InternalServerError };
    };
    base.ApplicationStartup(container, pipelines);
}

我在这里做错了什么？
