想要将重复的JSON对象转换为cypher语句，该语句将创建具有4个唯一节点，3个关系的图形，如下面的示例json中所定义。n相反，我得到了3对节点，每对都有一个重复的节点另一对。

with "/var/lib/neo4j/import/FULL_METADATA_V3.json" as file
CALL apoc.load.json(file) YIELD value
UNWIND value.lineage AS lineage
CALL apoc.create.node(lineage.source.labels, lineage.source.attributes) yield node as src
CALL apoc.create.node(lineage.target.labels, lineage.target.attributes) yield node as trg
call apoc.create.relationship(src, lineage.action.relationship, lineage.action.attributes, trg) yield rel
return src, trg:
{"lineage" : [{
"source": {
"labels":["Node","Application"],
"attributes": {
"Name":"AppStep1",
"Type":"process"}
},
"action": {
"relationship": "OPERATION",
"attributes": {
"RunStep": 1,
"WorkflowOwner": "user1"}
},
"target": {
"labels":["Node","Application"],
"attributes": {
"Name":"AppStep2",
"Type":"process"}
}
}, {
"source": {
"labels":["Node","Application"],
"attributes": {
"Name":"AppStep2",
"Type":"process"}
},
"action": {
"relationship": "OPERATION",
"attributes": {
"RunStep": 2,
"WorkflowOwner": "user1"}
},
"target": {
"labels":["Node","Application"],
"attributes": {
"Name":"AppStep3",
"Type":"process"}
}
},{
"source": {
"labels":["Node","Application"],
"attributes": {
"Name":"AppStep3",
"Type":"process"}
},
"action": {
"relationship": "OPERATION",
"attributes": {
"RunStep": 3,
"WorkflowOwner": "user1"}
},
"target": {
"labels":["Node","Application"],
"attributes": {
"Name":"AppStep4",
"Type":"process"}
}
}
]
}
所需的输出是4个节点和3个关系，但是目前我正在获得3对节点，有关如何完成操作的任何建议？
