然后去请求生成售后单接口

https://api.weixin.qq.com/shop/ecaftersale/add

请求参数如下

{"out_order_id":5422636288806,"openid":"otIcp48nMZx_fSb9_G7AoJ14r9GI","orderamt":100,"out_aftersale_id":"592253930x8017124","product_info":{"out_product_id":"14537","out_sku_id":"28125","product_cnt":1},"refund_reason":"协商一致退款","refund_reason_type":8,"type":2}

此时报{

    "errcode": 2747002,

    "errmsg": " 参数错误"

}

是什么原因呢
