Cannot Read Property 'length' of undefined

Hi,

I have been working with the REST API client interface for Neo4J. i am getting issue while fetching (or) inserting data to the neo4j through REST API client interface,
it causes problem in node_modules/neo4j/graphdatabase.js line 204 
for (i = _i = 0, _len = results.length; _i < _len; i = ++_i) {
....
}
It causes error as cannot read property length of undefined
Do u have any idea ?
