向层添加节点时Neo4j Spatial服务器错误500

Question

我正在使用Neo4j 2.2.2的Spatial插件，并设法按照指南http://neo4j-contrib.github.io/spatial/#spatial-layers创建空间索引。

:POST   http://localhost:7475/db/data/ext/SpatialPlugin/graphdb/addSimplePointLayer
{
  "layer" : "geom",
  "lat" : "lat",
  "lon" : "lon"
} 

:POST http://localhost:7474/db/data/index/node/
{
  "name" : "geom",
  "config" : {
    "provider" : "spatial",
    "geometry_type" : "point",
    "lat" : "lat",
    "lon" : "lon"
  }
}

我预先存在未连接的节点，其中包含多个标签＆＃39; DB_2＆＃39;和＆＃39;地址＆＃39;和属性＆＃39; name＆＃39;，＆＃39; lon＆＃39;和＆＃39; lat＆＃39;，当我尝试将这些节点添加到空间索引时，我得到一个错误，但是如果我创建一个没有任何标签的节点，那么只是＆＃39; lon＆＃39;和＆＃39; lat＆＃39;它似乎没有任何错误。

:POST http://localhost:7474/db/data/ext/SpatialPlugin/graphdb/addNodeToLayer
{
  "layer" : "geom",
  "node" : "http://localhost:7474/db/data/node/{id}"
}

我不确定它是否与我的节点标签或属性有任何关系，因为我无法从指南或其他示例中找到任何迹象表明这可能是一个问题。

提前感谢您的帮助！
