Hi experts,

I have developed an API and I am expecting to get request value from external application in the following format:

{
  "_leaveDetails": [
    {
      "personnelNumber": "PN001",
      "leaveType": "SICK"
    },
    {
      "personnelNumber": "PN002",
      "leaveType": "SICK"
    }
  ]
}

Not sure where I am wrong, my service class nothing reading from the JSON payload. always this bringing the null value.

Need your guidance to fix this issue.

I am thinking either JSON payload structure is wrong or List contract class signature is wrong or service class parameter is wrong.

List class signature:

[DataMemberAttribute('_leaveDetails'), DataCollectionAttribute(Types::Class,
classStr(XXXChildRequest))]
public List parmLeaveDetailList(List _leaveDetailList = _leaveDetails)

Service class signature

public str processAbsenceRequest(XXXParentListRequest _leaveDetails) // List class

I wrote following code but getting error while accessing from service class:

Request class:

[DataContractAttribute]
public class XXXChildRequest
{
    str   leaveType;
    str         personnelNumber;
    List        leaveDetailList;

    [
        DataMemberAttribute('Leave Type')
        //SysOperationDisplayOrderAttribute('1'),
        //SysOperationLabelAttribute(literalStr('Leave Type'))
    ]
    public TransDate parmLeaveType(Str _leaveType = leaveType)
    {
        leaveType = __leaveType;

        return leaveType;
    }

    

    [
        DataMemberAttribute('Personnel Number')
        SysOperationDisplayOrderAttribute('2'),
        SysOperationLabelAttribute(literalStr('Personnel Number'))
    ]
    public str parmPersonnelNumber(str _personnelNumber = personnelNumber)
    {
        personnelNumber = _personnelNumber;

        return personnelNumber;
    }

    
}

List Contract class:

[DataContractAttribute]
public class XXXParentListRequest
{

List _leaveDetails;

public void new()
{
_leaveDetails = new List(Types::Class);
}

[DataMemberAttribute('_leaveDetails'), DataCollectionAttribute(Types::Class,
classStr(XXXChildRequest))]
public List parmLeaveDetailList(List _leaveDetailList = _leaveDetails)
{
_leaveDetails = _leaveDetailList;
return _leaveDetails;
}
}

Service class:

[SysEntryPointAttribute]
public class XXXRequestService
{
    public str processAbsenceRequest(XXXParentListRequest _leaveDetails) // List class
    {

        List leaveList;
        ListEnumerator listEnum;

       // Code to get list request value

   
        }
        return jsonString;
    }

}
