CakePHP 3.5 400 Bad Request

Я разрабатываю CakePHP с конечной точкой GraphQL, построенной на Webonyx GraphQL-PHP пакет. Проблема в том, что методы post и multipart возвращают 400 неверных запросов. Сначала я думал, что это из-за того, что запрос предполётной обработки был обработан, а последующие действия проигнорированы или возникла простая проблема cors, но после обширной отладки и модификации кода. Я определил, что они настроены правильно. я использую этот Плагин для управления предполетным запросом. Конфигурация по умолчанию позволяет все источники и проблемы сохраняются.

Метод действия, обрабатывающий запрос, выглядит так.

    public function index(){
$this->autoRender = false;

$data = $this->request->input('json_decode');

if(!$data) {
$data = $this->request->getParam('?');
}

if(!$data) $data = [];
$data += ['query' => null, 'variables' => null];
$result = $this->GraphQL->query($data);

$this->response = $this->response
->withHeader('Access-Control-Allow-Origin', '*')
->withHeader('Access-Control-Allow-Methods', ['GET', 'POST', 'OPTIONS'])
->withHeader('Access-Control-Allow-Credentials', 'true')
->withHeader('Access-Control-Max-Age','8600')
->withType('application/json')
->withStringBody(json_encode($result));
return $this->response;
}

Но это не причина проблемы. POST и MULTIPART даже не включаются в эту функцию, пока не вернут ошибку. Я тестировал конечную точку с помощью GraphiQL Feen.

Это итоговая трассировка стека из журнала ошибок.

Также в нем говорится, что _Token отсутствует в данных запроса, но я отключаю CSRF в своей функции beforeFilter следующим образом.

public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
$this->Auth->allow('index');
$this->eventManager()->off($this->Csrf);
}

С другой стороны, будет ли использование соединения debug_kit, упомянутого в первых трех строках, более подробным выводом?
