多商户版v2.1体验版小程序支付创建订单报错

在配置好支付参数以后，提交订单支付时报错：

#0 [0]ArgumentCountError in BaseClient.php line 33

Too few arguments to function crmeb\services\easywechat\BaseClient::__construct(), 1 passed in /home/crmeb/services/easywechat/miniPayment/Client.php on line 37 and exactly 2 expected

class BaseClient extends AbstractAPI

{

   protected $app;

   const KEY_LENGTH_BYTE = 32;

   const AUTH_TAG_LENGTH_BYTE = 16;

   protected $isService = true;

   public function __construct(AccessToken $accessToken, $app)

   {

       parent::__construct($accessToken);

       $this->app = $app;

   }

========================================

Call Stack

in BaseClient.php line 33

at BaseClient->__construct() in Client.php line 37

这个client.php 37行的内容是：

parent::__construct($accessToken);

这个父类的构造函数不是2个参数吗，为啥这里调用的时候只传了一个，我没改过任何一行代码啊
