Neo4j REST API - create unique node

I am trying to use the REST API to create a unique node. However, I am getting the error about requiring the key 'uri' (see below). Based on the documented examples, this call creates and indexes the newly created node ... so there should not be a 'uri' paramater. My request and response are below. What am I doing wrong?

REQUEST:

http://www.somemachine.com:7474/db/data/index/node/idxHost?unique=get_or_create

{
    "key": "name",
    "value": "HOST",
    "properties": {
        "type": "company",
        "name": "HOST",
        "sequence": 1
    }
}

RESPONSE:

state:400, body:

{
  "message" : "Missing required key: \"uri\"",
  "exception" : "BadInputException",
  "fullname" : "org.neo4j.server.rest.repr.BadInputException",
  "stacktrace" : [ "org.neo4j.server.rest.repr.formats.JsonFormat.readMap(JsonFormat.java:92)", "org.neo4j.server.rest.web.RestfulGraphDatabase.addToNodeIndex(RestfulGraphDatabase.java:802)", "java.lang.reflect.Method.invoke(Method.java:601)" ],
  "cause" : {

  }
}

According to the doc, in 1.8 the url ends with '?unique' whereas in 1.9 is '?uniqueness=get_or_create'

I think this may cause your error.

see for 1.8: http://docs.neo4j.org/chunked/stable/rest-api-unique-indexes.html#rest-api-add-a-node-to-an-index-unless-a-node-already-exists-for-the-given-mapping

and 1.9: http://docs.neo4j.org/chunked/milestone/rest-api-unique-indexes.html
