Steps to Reproduce
Not Applicable.
Root Cause
A defect in Pegasystems’ code or rules. Most FrequentlyUsedMap code has a bug that results in this error when Engine checks for localized rulesets. If your Requestor Type records reference a custom Access Group that has localized rulesets, then that can result in the behavior.
Resolution
Perform the following local-change:
Make sure that localized rulesets are not added to out of the box Requestor Types' Access Groups before performing an upgrade. This issue will be fixed in the future Pega 7.x release.
