HI All,

We have used declare index in our project with "source page context" as nested page list. We noticed below error in pega logs. There is no standards pattern to reproduce below as it appears randomly.

Did anyone encountered below error and if so what is the fix for this?

Also, we already have the property "tyKeyWordList"  defined at "@baseclass".
