I am getting below error when trying to execute my workflow. It is failing in Set Transaction Status activity in SetTransactionStatus.xaml. Can someone please help what could be the reason?
An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.NullReferenceException: Object reference not set to an instance of an object.
