I am beginner with Neo4j Rest API. I am using [Everyman](https://github.com/jadell/neo4jphp) php library to develop my application. I have problem with creating node with labels. 

```
use Everyman\Neo4j\Client,
    Everyman\Neo4j\Transport,
    Everyman\Neo4j\Node,
    Everyman\Neo4j\Relationship;
use Everyman\Neo4j\Cypher;

public function indexAction()
{  
    $client = new Client('localhost', 7474);
    $user = new Node($client);
    $user->setProperty('name', 'Rohan Chingula');
    $user->save()->addLabels(array('Users'));
}

```

while I run code I am getting

>  Message:
>  Cannot set a non-label
