我想遍历从源节点到深度（路径长度）为5的图形并返回包含特定关系类型的路径（在我的情况下，我将该类型名称存储在RelationLabel变量中）并打印所有这些路径，但我在lastRelationshipTypeIs（RelationshipType.withName（RelationLabel））中得到错误，如下所述 . 我怎么穿越？

Code :

TraversalDescription td = graphDb.traversalDescription();
 td.depthFirst()
.evaluator( Evaluators.fromDepth( 1))
.evaluator(Evaluators.toDepth(5))
.evaluator(Evaluators.lastRelationshipTypeIs(RelationshipType.withName(RelationLabel)))                 
.traverse(srcnode)
.forEach(System.out::println);

Error :
