采购申请单通过sdk上传文件，返回500错误但是没有错误原因，如何排查问题呢。

{"ErrorCode":"500","IsSuccess":false,"Errors":[],"SuccessEntitys":[]}

报文如下：

{

"FileName": "PLM物料.txt",

"FormId": "PUR_Requisition",

"IsLast": true,

"InterId": "100012",

"BillNO": "CGSQ20230824008",

"AliasFileName": "test",

"SendByte": "PLM 物料 保存
一、请求参数说明：
1.formid：业务对象表单Id，字符串类型（必录）
2.opNumber：操作编码，字符串类型（必录）
3.data：JSON格式数据（详情参考JSON格式数据）（必录）
     3.1.Parameters：参数集合，字符串类型（非必录） 注（其值传给操作选项）
     3.2.Numbers：单据编码集合，数组类型，格式：[No1,No2,...]（使用编码时必录）

// 使用webapi引用组件Kingdee.BOS.WebApi.Client.dll
K3CloudApiClient client = new K3CloudApiClient("http://win-oadata/k3cloud/"); 
var loginResult = client.ValidateLogin("64d1ed86c8335d","Administrator","888888",2052);
var resultType = JObject.Parse(loginResult)["LoginResultType"].Value<int>();
//登录结果类型等于1，代表登录成功
if (resultType == 1)
{
	 client.Save("PLM_PDM_1010000000000000000","Save","{"Parameters":"","Numbers":[],"Ids":"","Model":{"FID":0,"FIcon":"","FCode":"","FSpecification":"","FName":"","FModel":"","FCategoryID":{"FCODE":""},"FErpClsID":"","FCommonType":"","FLifeCircleStage":"","FCreateDate":"1900-01-01","FBATCH":0,"FCreatorId":{"FUserID":""},"FExtensionMark":"false","FModifyDate":"1900-01-01","FMaxVerNO":"","FMinVerNO":"","FModifierId":{"FUserID":""},"FBuildVer":0,"FMaxVer":0,"FVerNO":"","FIsCheckOut":"false","FMinVer":0,"FFolderID":{"FCode":""},"FRemark":"","FCheckOutor":{"FUserID":""},"FCbCertification":"false","FIsFlow":0,"FBASEOBJECTREF":0,"FErpMaterialID":0,"FIsOwner":"false","FOwnerUser":{"FUserID":""},"FChangeObjectId":{"FCODE":""},"FIsChange":"false","FIsChangeObject":"false","FAllowShare":"false","FExpiryDate":"1900-01-01","FEffectiveDate":"1900-01-01","FIsVirtualDoc":"false","FECNFormId":{"FCODE":""},"FCreateOrgId":{"FNumber":""},"FGlobalShare":"false","FIdentityKey":"","FVerCreatorId":{"FUserID":""},"FLastCheckin":{"FUserID":""},"FLastCheckinDate":"1900-01-01","FFLOWNUMBER":"","FPROCDEFID":{"FDISPLAYNAME":""},"FFLOWSTATUS":"","FFLOWORIGINATORID":{"FUserID":""},"FFLOWCREATETIME":"1900-01-01","FISINTERNALSAVE":"false"}}");
