BPM error-RUL-05721: The result type of the expression is "String" but should be "List"

Summary:

Hello,

I am trying to use this condition in BPM for absence approval task for checking if the 'Regional manager' is active:

GetManager("REGIONAL_MANAGER",Task.payload.getRequestorInformationByUserNameResponse.result.assignmentStatusType) IS ACTIVE

It give me following error:

RUL-05721: The result type of the expression is "String" but should be "List".

RUL-05717: The identifier "ACTIVE" is not valid here.

Similar expression below works fine:

GetManager("REGIONAL_MANAGER",Task.payload.getRequestorInformationByUserNameResponse.result.requestManager) is ""

Please help.

This is to solve the problem of awaiting approval status when the local manger is inactive.

Thanks.
