我在 .net 应用程序中使用 ServiceStack (3.9.32)

我正在使用 XSD2Code 生成基于 XSD 创建请求

注册路线时， 

Routes.Add<ahdc.core.entities.external.order.LabOrder>("/LabOrder", "POST")
                .Add<Request.ResultPoll>("/ResultPoll/{uid*}", "GET")
                .Add<Request.ResultPoll>("/ResultPoll", "POST")
                .Add<Request.Result>("/Result/{externalId*}", "GET")
                .Add<Request.Result>("/Result", "POST")
                .Add<Request.LabReport>("/LabReport", "GET")
                .Add<Request.OrderedTests>("/OrderedTests", "POST")
                .Add<Request.OrderedTests>("/OrderedTests/{externalId*}", "GET")
                **.Add<ahdc.external.Request.HL7Order.OPL_O37>("/HL7LabOrder", "POST");**

粗体部分是新行。服务堆栈抛出此异常：

我很困惑为什么。
