When we tested our migrated claims based workflow on to SP2013 we get the following error message:


System.ArgumentException: Invalid field name. {f9c2546c-f40b-46d5-8bac-9an11cc7d640} /sites/..../WorkflowTasks at Microsoft.SharePoint.SPFieldCollection.GetFieldById(Guid fieldID, Boolean bThrowException) at Microsoft.SharePoint.SPListItem.get_Item(Guid fieldID) at Nintex.workflow.HumanApproval.Approver.LoadAvailableOutcomes()


The Nintex workflow was developed on SP2010 and was working before and after the migration on that SP2010 server but the copy on our SP2013 test server gives a correlation id error message which we traced to the above message.  The correlation id message popped up after clicking on the yellow band to "update this task" at the top of a form in InfoPath filler 2013 (and 2010).

    Any ideas to what might be the problem?
