物流助手发起下单，向这个地址发起请求，

https://api.weixin.qq.com/cgi-bin/express/business/order/add?access_token=

这个接口，平时都是好的，如果订单是2件商品的，返回了以下错误，这是为啥呢？这个具体是什么错误

微信物流助手发货失败：{"errcode":9300501,"errmsg":"delivery logic fail","delivery_resultcode":20006,"delivery_resultmsg":"货物数量、重量、尺寸不正确或者不合理","waybill_data":[]}

货物数量和重量与一件一样的时候也是错误的，乘上件数也是错误的。

之前使用圆通快递，多件是可以发货的，现在用的是中通快递，出现这个问题
