error on calling getTransport() ..

[JugalSA]

Call to a member function getTransport() on array in C:\xampp\htdocs\purplle\application\libraries\Everyman\Neo4j\Command.php on line 101

I am not able to figure this out.

Lines of code are::

$client = new Everyman\Neo4j\Client('localhost', 7474);

    $arthur = $client->makeNode();
    $arthur->setProperty('name', 'Arthur Dent')
            ->setProperty('mood', 'nervous')
            ->setProperty('home', 'small cottage')
            ->save();

    $arthurId = $arthur->getId();
    print_r($arthurId);
    exit;
