Exception when calling AllApi->salePost

Me pidieron que haga un ejemplo de una Venta con un cliente generado con un contrato Swagger. A la hora de correr mi ejemplo, me sale este error:

• Description: Se debe realizar una prueba de la realización de una Compra *——————————————————————————————————————————————————————— Exception when calling AllApi->salePost: [400] Client error: POST https://testcodi.multipay.mx:30801/Payments/Authorize/5.3.0/Sale resulted in a 400 Bad Request response: {"CardReadModeResponse":{"ResponseAction":"Refuse","ResponseCode":"4006","ResponseMessage":"Tipo de operacion no soporta (truncated…) Exception when calling PaymentApi->authorizeSalePost: [400] Client error: POST https://testcodi.multipay.mx:30801/Payments/Authorize/5.3.0/AuthorizeSale resulted in a 400 Bad Request response: {"localContextMessageIDResponse":{"ResponseAction":"Refuse","ResponseCode":"4006","ResponseMessage":"Tipo de operacion n (truncated…)

Este es mi código:

<?php

      //require_once('SwaggerClient-php/lib/Model/Sale.php');
      require_once('SwaggerClient-php/lib/Model/SaleResponse.php');

      $apiInstance = new SwaggerClientApiPaymentApi(
      new GuzzleHttpClient()
      );

      $body = new SwaggerClientModelSale();


      $body->setCardReadMode('B');
      $body->setCardNumber('4540245431234563126');
      $body->setCardExp('1120');
      $body->setSecurityCode('333');
      $body->setAmount(5000);

      $body->setPOSIdentification('1');
      $body->setReadingDeviceType('PinpadVx820Terminal');
      $body->setFacilityPayments(12);

      try {
         $result = $apiInstance->salePost($body);
         print_r($result);
      } catch (Exception $e) {
          echo 'Exception when calling AllApi->salePost: ', $e->getMessage(), PHP_EOL;
      }


       $transaction = new SwaggerClientModelSaleResponse();

       $authorize_sale = new SwaggerClientModelAuthorizeSale();
        try {
           $result = $apiInstance->authorizeSalePost($authorize_sale);
           print_r($result);
        } catch (Exception $e) {
           echo 'Exception when calling PaymentApi->authorizeSalePost: ', $e->getMessage(),
