How to properly validate JSON request in symfony 3.4

As the title says. How can I validate JSON request in symfony?

I found this package for validating JSON but it doesn't work with request object.

<?php

namespace AppBundle\Controller;

use Psr\Log\LoggerInterface;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use JsonSchema\Validator;


class ApiController extends Controller
{


    /**
     * @Route("/api/store-data", name="store-data", methods={"POST"})
     * @param Request $request
     * @param LoggerInterface $logger
     * @return \Symfony\Component\HttpFoundation\Response
     */
    public function storeDashboardLayout(Request $request, LoggerInterface $logger)
    {
        $validator = new Validator();
        $validation = $validator->validate(
            $request,
            (object)[
                "type" => "object",
                "properties" => (object)[
                    "new_layout" => (object)[
                        "type"=> "string"
                    ]
                ],
                "required" => [
                    "new_layout"
            ]
        ]);

        if(!$validator->isValid()){
            // json is not valid do something
        }
    }
}

Whenever I send a POST request to that endpoint with correct value ({"new_layout": "blabla"}) it ends up in if clause - not valid.

What is a good approach to achieve that? Doesn't exist something like I could define how my incoming JSON would look like in comment section?

The only solution what I've found so far is to convert JSON request to associated array manually and then verify:

    $data = json_decode($request->getContent(), true);
    $validator = new Validator();
    $validation = $validator->validate(
        $data,
        (object)[
            "type" => "array",
            "properties" => (object)[
                "new_layout" => (object)[
                    "type"=> "string"
                ]
            ],
            "required" => [
                "new_layout"
        ]
    ]);

The only thing that needs to be done: Every "type" => "object" must be renamed to "type" => "array"
