学习论坛里的代码 function CancelPendingOrders() { var orders = exchange.GetOrders();//获取所有未完成的订单。

for (var j = 0; j < orders.length; j++) {
      exchange.CancelOrder(orders[j].Id, orders[j]);}//该函数的用途为取消某个Id的订单。

}

执行报错 2023-02-12 00:00:51 错误 TypeError: cannot read property ‘length’ of null at CancelPendingOrders (FILE:41) at main (FILE:125) 2023-02-12 00:00:51 Futures_OKCoin 错误 GetOrders: 401: {“msg”:“APIKey does not match current environment.”,“code”:“50101”}

请问是什么原因呢？谢谢
