求助：xt_trader.order_stock 和 xt_trader.order_stock_async 两个接口定价卖出报错

请教一个问题，能否帮忙解答一下，感谢~~~<br/>在调用异步下单接口xt_trader.order_stock_async进行股票固定价格卖出的时候报以下错误，同步下单的接口xt_trader.order_stock也是报同样的错误；<br />但是很奇怪的是同一个接口，固定价格买入，两个接口又没问题。<br/>seq = self.xt_trader.order_stock_async(account, stock_code, order_type, order_volume, price_type, price, strategy_name, order_remark)<br/>File "D:\DTClient\xtquant\xttrader.py", line 418, in order_stock_async<br/>req.m_nOrderVolume = order_volume<br/>TypeError: (): incompatible function arguments. The following argument types are supported:<br/>1. (self: xtquant.xtpythonclient.OrderStockReq, arg0: int) -> None<br/>Invoked with: <xtquant.xtpythonclient.OrderStockReq object at 0x00000216AB8279F0>, 9.32

order_volume参数需要传一个init，检查下类型
