Hi everybody.
I hope all doing well.
last time I tried to apply an action to an activityInstance using wfgen web service as below:
POST /wfgen/ws/ProcessesRuntime.asmx/CompleteWebFormActivityInstance?impersonateusername=username HTTP/1.1
Host: 10.23.6.189
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Content-Length: 586
processInstanceId=24857&activityInstanceId=7&workflowContext=APPROVAL4_rbDecision4TEXT INOUTموافقةAPPROVAL4_dtVacationEndDateDATETIMEINOUT2021-01-25T00:00:00+02:00APPROVAL4_dtVacationStartDateDATETIMEINOUT2021-01-01T00:00:00+02:00
but I faced the below exception :
HTTP/1.1 500 Internal Server Error
System.Data.DuplicateNameException: A column named APPROVAL4_dtVacationEndDate already belongs to this DataTable.
I searched a lot in the forum and the web but I couldn’t find any answer.
kindly may you advice me to fix this error.
thanks in advance.
BR.
