Neptune does not support closures/lambdas: https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-differences.html#feature-gremlin-differences-lambda you would have to use pure Gremlin steps, thus
g.V().hasLabel('person')Gremlin standards compliance in Amazon Neptune - Amazon Neptune
