pv getting the value as [object object]

Hi All,

We are facing an issue where I have created a rule to fetch a group according to a pv from previous screen.

So the First node of the process calls that rule like this rule!getExcDirByTaskOwner(pv!taskOwner) but this rule is fetching me [object object] in process. When I test the same rule in Expression it is working fine and fetch the correct group. The value is getting displayed as Blank in the report due to this, which is causing issue.

I know it is an old problem in Appian Process models but need a solution or workaround for this.

Regards
