{

    "errcode": 1090020,

    "errmsg": "优惠券回调检验结果失败 rid: 61a6db38-078ac291-51e147fa"

}

这个应该需要怎么处理呢？

回调请求参数示例

<xml>
    <ToUserName>gh_abcdefg</ToUserName> 
    <FromUserName>oABCD</FromUserName> 
    <CreateTime>1627747200</CreateTime>
    <MsgType>event</MsgType> 
    <Event>open_product_receive_coupon</Event>
    <out_coupon_id>test_coupon</out_coupon_id>
    <request_id>test_coupon_request_id</request_id>
</xml>

我可以拿到这个值
