java單商戶版關于七牛云配置的所屬地域問題

根據文檔寫的是可不填寫，但是后臺貌似不填寫不可保存，

寫對應的低于有報錯，比如華東-浙江2  或者華東-浙江  拼音，漢字，以及網上提供的簡寫都嘗試了，都不行！

報錯如下：

"app": "Crmeb",
                   "timestamp":"2023-07-07 23:22:27.145",
                   "level": "INFO",
                   "thread": "http-nio-20400-exec-29",
                   "class": "c.z.s.service.impl.QiNiuServiceImpl",

{
                   "app": "Crmeb",

{"error":"incorrect region, please use up-cn-east-2.qiniup.com, bucket is: qianjinyaowang"}" }

根據網上所反饋七牛云配置華東區域的編碼如下：

 Zone.zone0

問題：請問七牛云的所屬地域應該怎么配？
