[rules-users] No such field org.optaplanner.core.config.heuristic.selector.value.chained.SubChainSelectorConfig.entitySelector

when I use this code: <subChainChangeMoveSelector> <subChainSelector> <entitySelector> <entityClass>model.ScheduleBlockPeriod</entityClass> </entitySelector> <minimumSubChainSize>2</minimumSubChainSize> <maximumSubChainSize>40</maximumSubChainSize> </subChainSelector> <valueSelector> <variableName>nextScheduleBlockPeriod</variableName> </valueSelector> <selectReversingMoveToo>true</selectReversingMoveToo> </subChainChangeMoveSelector> I get the following error:
