Steps to Reproduce

Verify the logs.


Root Cause

A defect in Pegasystems’ code or rules. A property remove on the pxOperatorSkillsCount property is present in step 7 of the SetWorkInfo activity (Code-Pega-Requestor). The NullMyStepPage exception occurs if the OperatorID page is unavailable on the Clipboard.



This issue is addressed in Pega 8.4.3 and Pega 8.5.1.

Alternatively, as a local-change:
Add a pageExists check.
