Steps to Reproduce



RuleNotFound exception on screen when the Wrap-Up of the Interaction was performed.

Root Cause



Rule Not Found: Rule-Obj-Activity @baseclass.CloseWorkItem

For diagnosing the issue, end users were unable to provide the Fiddler trace or Tracer dump for the non-working scenario. In the working scenario, this activity was not called however in the non-working scenario, an unexpected call was made to this activity CloseWorkItem.


Resolution



Local-change was proposed which helps overcome issue - create an activity (CloseWorkItem) with applies to class as @baseclass in the custom application ruleset with authenticate unchecked and “May Start” option checked. This activity would have no steps and do nothing -- it merely stops the error from breaking the flow.
