Javascript/Neo4j-将GeoJSON对象存储为节点属性

我试图使用以下cypher语句将GeoJSON对象存储为Neo4j数据库中节点的属性，其中

boundary.boundary

是特征集合，而

boundary.centroid

是点：

UNWIND $fieldsToCreate AS obj

MERGE (f:Field {
  id: apoc.create.uuid(),
  xId: obj.fieldXId,
  legacyId: obj.legacyId,
  name: obj.name
})

FOREACH (boundary IN obj.boundary |
  CREATE (b:Boundary) SET
    b.id = apoc.create.uuid(),
    b.boundary = boundary.boundary,
    b.centroid = boundary.centroid,
    b.name = boundary.name
  MERGE (f)-[:HAS_BOUNDARY { from: datetime() }]->(b)
)

RETURN f AS field

返回以下错误：

Neo4jError:属性值只能是基元类型或基元类型的数组

将GeoJSON存储到Neo4j数据库的正确方法是什么
