Neo4j 3.0.1 - org.neo4j.ogm.exception.CypherException: Ошибка при выполнении Cypher

Question

Я двигаюсь от SDN 3 до SDN 4 и от Neo4j 2.3 до 3.0.1

Прямо сейчас мой тест не на следующий Cypher запрос:

MATCH (d:Decision)<-[:VOTED_FOR]-(vg:VoteGroup)-[:VOTED_ON]->(c:Criterion) WHERE id(d) = {decisionId} AND id(c) = {criterionId} WITH vg MATCH vg-[:CONTAINS]->(v:Vote)-[:CREATED_BY]->(u:User) WHERE id(u) = {userId} RETURN v 

со следующим исключением:

Этот запрос работает отлично на Neo4j 2.3

Что может быть причиной этого и как его исправить?

Answer 1

Я подозреваю, что это потому, что Neo4j 3 больше не любит голые узлы. Я изменил MATCH vg на MATCH (vg):

MATCH (d:Decision)<-[:VOTED_FOR]-(vg:VoteGroup)-[:VOTED_ON]->(c:Criterion) 
WHERE id(d) = {decisionId} AND id(c) = {criterionId} 
WITH vg 
MATCH (vg)-[:CONTAINS]->(v:Vote)-[:CREATED_BY]->(u:User) 
WHERE id(u) = {userId} 
RETURN v
