For the first query, p = xxx such kind of query is not supported yet. We have no plan to support it in a short time. We should update the doc: https://graphscope.io/docs/latest/interactive_engine/neo4j/supported_cypher, to include more known limitations @shirly121 .

For the second query, I will fix it via #3538 , BUT the returned result(only return the last vertex) will still different from the standard neo4j cypher query result(returning all vertices/edges on path). See #3537
