"action_name": "QR_MULTIPLE_CARD",

"multiple_card": {
"card_list": [{

},
{
"code": "2392583482",
"outer_str": "12b"
}
]
}
}
}I read the interface document, and the default is 365 days without expiration. However, in practice, I found that this kind of QR code containing multiple card coupons will expire in a few months, and the scan will show that the QR code has expired. What kind of pit is this?
