payload is invalid for laravel_session decrypt

Question

I'm trying to decrypt laravel_session but the following error occur:

An error has occurred: The payload is invalid.

simply I'm using Rachet and I'm trying to call the authorized user, so I got the cookies in httpRequest using the following:

    public function onOpen(ConnectionInterface $conn) {

        $this->clients[$conn->resourceId] = new Client();
        $this->clients[$conn->resourceId]->conn = $conn;


        $cookiesRaw = $conn->httpRequest->getHeader('Cookie');

        $cookies = [];
        if(count($cookiesRaw))
        {
            $cookies = \GuzzleHttp\Psr7\parse_header($cookiesRaw)[0]; // Array of cookies
        }

 // Get the laravel's one
        $laravelCookie = $cookies[Config::get('session.cookie')];

$idSession = Crypt::decrypt($laravelCookie);
        echo "\n cookie is ";
        print_r($idSession);

}

The Crypt::decrypt($laravelCookie); is causing the error, I've tried to use:

    $cookie_contents = json_decode( base64_decode( $laravelCookie, true ));
    $value = base64_decode( $cookie_contents->value );
    $iv = base64_decode( $cookie_contents->iv );
    $clear = unserialize( \openssl_decrypt($value, \Config::get( 'app.cipher' ), \Config::get( 'app.key' ), OPENSSL_RAW_DATA, $iv));
    echo "Cookie contents (Session ID): $value\n";

but it is also causing The payload is invalid.

How can I decrypt this laravel_session in order to get user session id !

I want to get the Auth user via this session.

I've searched a lot in stack-overflow and google, but all the cases didn't match mine.

Note: I'm using SESSION_DRIVER=file

Laravel provides a way to grab your session id:

use Illuminate\Support\Facades\Session;

$sessionid = Session::getId();
