Neo4j Spatial server error 500 when adding nodes to layer

Question

I am using the Spatial plugin for Neo4j 2.2.2 and have managed to create a spatial index by following the guide http://neo4j-contrib.github.io/spatial/#spatial-layers.

: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"
  }
}

I have pre-existing unconnected nodes with multiple labels 'DB_2' and 'Address' and properties 'name', 'lon' and 'lat', when I try to add these nodes to the spatial index I get an error but if I create a node without any labels and just 'lon' and 'lat' properties it seems to work without any errors.

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

I not sure if it has anything to do with my node labels or properties as I can't find any indication from the guide or other examples suggesting that this could be a problem.

Thanks for any help in advance!
