خطای استیمول

سلام
این خطا رو وقتی میخوام گزارش استیمول رو بگیرم دارم.
وقتی با sp دیتا رو میخونم مشکلی نیست اما به دلایلی میخوام از sp استفاده نکنم و سمت کد دیتا رو به گزارش پاس بدم اما خطا میده :

System.ArgumentNullException: Value cannot be null. Parameter name: value at System.Enum.TryParseEnum(Type enumType, String value, Boolean ignoreCase, EnumResult& parseResult) at System.Enum.Parse(Type enumType, String value, Boolean ignoreCase) at Stimulsoft.Report.Mvc.StiMvcViewer.SaveReportObjec t(HttpContextBase httpContext, StiReport report) at Stimulsoft.Report.Mvc.StiMvcViewer.GetReportSnapsh otResult(StiReport report) at SPMS.Controllers.ReportController.PackageCommandPr int(String startDate, String endDate, Int32 profileId) in D:\Projects\SPMS\SPMS\Controllers\ReportController .cs:line 83




نکته جالب اینجاست که این خطا رو برای گزارش خالی هم دارم .
