When creating a K2 Package, an error occurs which stops you from proceeding.
The following error will occur:
"System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object."
Please install the K2 4.7 May Cumulative Update and recreate your K2 Package.
