RestAPI method put and patch don't work

Cakephp 3 has bug with Rest API!
Methods as get, post, delete work ok and receive data in $this->request->data!
But method put and patch don’t work, because request receive empty data!
All data receive in in params as varible “?” ($this->request->params[’?’)]

And I must to write

public function edit($id) {

    $data = !empty( $this->request->getData() ) ? $this->request->getData() : $this->request->params['?'];
    $payment = $this->Payments->get($id);
    if ($this->request->is(['patch', 'post', 'put'])) {
        $payment = $this->Payments->patchEntity($payment, $data);
        if ($this->Payments->save($payment)) {
            $message = 'Saved';
        } else {
            $message = 'Error';
        'message' => $message,
        '_serialize' => ['message']


Do anyone how fix this bug?

And remember Putin - Huylo!
