Can't query Neo4J database using Neo4J-PHP- Unsupported Media Type

So I installed Neo4J alongside the Neo4J-PHP-Client found on GitHub here : https://github.com/graphaware/neo4j-php-client

I can query my database through the Desktop App and everything I do takes effect. I managed to connect to my database through PHP successfully, no errors at all. The problem arises when I try to run a query through PHP, it doesn't work at all, despite the very same query working perfectly if I run it through the Neo4J Desktop App.

Here's my code snippet, also I used the query example given in the GitHub post of Neo4J-PHP-Client :

<?php
 require_once './vendor/autoload.php';

 use GraphAware\Neo4j\Client\ClientBuilder;

 $client = ClientBuilder::create()
   ->addConnection('default', 'http://neo4j:parola@localhost:7474')
   ->build();
 $client->run('CREATE (n:Person)'); 

?>

The error I get is :

Fatal error: Uncaught Http\Client\Common\Exception\ClientErrorException: Unsupported Media Type in C:\xampp\htdocs\licenta\vendor\php-http\client-common\src\Plugin\ErrorPlugin.php:72
Stack trace: #0 C:\xampp\htdocs\licenta\vendor\php-http\client-common\src\Plugin\ErrorPlugin.php(54):

C:\xampp\htdocs\licenta\vendor\php-http\client-common\s in C:\xampp\htdocs\licenta\vendor\php-http\client-common\src\Plugin\ErrorPlugin.php on line 72

I really can't wrap my head around it, any help is greatly appreciated. Thanks in advance!
