ASN Retrieve遇到报错

5月8号凌晨在生产环境进行ASN Retrieve的时候出现报错，

调用的URL是transact.ti.com/.../

报错信息如下

{
"errors" : [
{
"errorCode" : "TI-TXT-008",
"type" : "INFO",
"reason" : "ASN information unavailable",
"message" : "Shipment is complete. ASN information is no longer available. If further assistance is needed, contact TI API Support ( https://api-portal.ti.com/support )."
}
]
}

目前已经能够通过URL正确获取到数据，但是想明确当时这个错误是什么原因导致的，麻烦帮忙核查下
