I'm trying to integrate infoPath form with Nintex workflows with two important webservices :a. GetRunningWorkflowTasksForCurrentUser(string fileUrl)
b. ProcessTaskResponse(string comments, Outcome outcome, int spTaskId)
when my workitem reached to Request approval task, i open the form and call "GetRunningWorkflowTasksForCurrentUser" function is work correctly because Sharepoint Task ID and many parameters is returned but when i call the "ProcessTaskResponse" with correct input function for Approve or Reject the form to continue the workflow, i was faced to below infopath error:
The query cannot be run for the following DataObject: ProcessTaskResponse
InfoPath cannot run the specified query.
The SOAP response indicates that an error occurred on the server:
Server was unable to process request. ---> Item does not exist. It may have been deleted by another user.
please help me about mentioned problem.
