Why is Telegram webHook giving 500 error in yii2?

Question

Yii

Hello!

I’m trying to make a telegram webhook, I
set the link itself, the status on the link is OK
when I try to pull the link manually - the message arrives in the cart, everything is OK,
but when I send the message to the cart, I don’t receive a response, and the getWebhookInfo status shows 500:
Wrong response from the webhook: 500 Internal Server Error

getWebhookInfo:

{"ok":true,"result":{"url":"https://domain.ru/telegram/get","has_custom_certificate":false,"pending_update_count":39,"last_error_date":1643103534,"last_error_message":"Wrong response from the webhook: 500 Internal Server Error","max_connections":40,"ip_address":"xxx.xxx.xxx.xxx"}}

Controller code:

class TelegramController extends BaseController
{
  public function behaviors()
    {
        return [
            'verbs' => [
                'class' => VerbFilter::className(),
                'actions' => [
                    'get' => ['post'],
                ],
            ],
        ];
    }

  public function beforeAction($action)
  {            
      if ($action->id == 'get') {
            $this->enableCsrfValidation = false;
        }
        
        return parent::beforeAction($action);
  }

  public function actionGet()
  {
    TelegramBot::message('000000', 'ok');
  }
}

It feels like it should be allowed to accept POST from third-party sources, but I kind of turned off enableCsrfValidation, but it doesn’t work, something is missing. Tell me pliz)
