Can not use my json

Hello

i use this code on my site :

$content = file_get_contents("php://input");
$uu=json_decode($content);

i just added that :

$jsonq = new Jsonq($content);

The json_decode works fine

But for the jsonq, i get this error.

( ! ) Fatal error: Uncaught Nahid\JsonQ\Exceptions\InvalidJsonException: Invalid JSON format in E:\wamp64\www\ga\vendor\nahid\jsonq\src\Jsonq.php on line 30
( ! ) Nahid\JsonQ\Exceptions\InvalidJsonException: Invalid JSON format in E:\wamp64\www\ga\vendor\nahid\jsonq\src\Jsonq.php on line 30

Someone know what to do ?

Thank you.
