在我的Spring Data Neo4j应用程序中，我实现了创建节点和关系的测试。到目前为止一切正常。
为了提高应用程序性能，我想尝试使用关系属性的手动索引。
我添加了以下Neo4j APOC触发器，必须在manuall index中添加和删除关系属性：
CALL apoc.trigger.add('HAS_VALUE_ON_ADD_TO_INDEX', 'UNWIND {createdRelationships} AS r MATCH (d:Decision)-[r:HAS_VALUE_ON]->(ch:Characteristic)
CALL apoc.index.addRelationship(r, keys(r)) RETURN count(*)', {phase:'after'});
CALL apoc.trigger.add('HAS_VALUE_ON_REMOVE_FROM_INDEX', "UNWIND {deletedRelationships} AS r MATCH (d:Decision)-[r:HAS_VALUE_ON]->(ch:Characteristic)
CALL apoc.index.removeRelationshipByName('HAS_VALUE_ON', r) RETURN count(*)", {phase:'after'});
一旦我添加了这些索引，我的测试（如上所述）就会失败，并出现以下异常：
org.springframework.dao.InvalidDataAccessApiUsageException: Error executing triggers {HAS_VALUE_ON_REMOVE_FROM_INDEX=Unable to load NODE with id 3.}; nested exception is org.neo4j.ogm.exception.TransactionException: Error executing triggers {HAS_VALUE_ON_REMOVE_FROM_INDEX=Unable to load NODE with id 3.}

我做错了什么以及如何解决？
已更新
我使用Spring Boot测试：
@RunWith(SpringRunner.class)
@SpringBootTest(classes = { TestApplication.class })
public class DecisionCharacteristicIT {
@Test
public void testRelationshipValueTriggerAndIndex() {
// test logic
}
}
