Bug: Errors when I try to use both @PlanningListVariable and @PlanningVariable in one project

Describe the bug

When I try to use both @PlanningListVariable and @PlanningVariable in one project, I got error below.
Caused by: java.lang.IllegalArgumentException: The config (ValueSelectorConfig(null)) has no configured variableName for entityClass (class com.tmtblback.dto.LessonDto) and because there are multiple variableNames ([room, studentGroups, timeslot]), it cannot be deduced automatically.

As this is a duplicate, I will close this one.
Thank you for reporting anyway, @seallijian!
