java单商户版关于七牛云配置的所属地域问题

根据文档写的是可不填写，但是后台貌似不填写不可保存，

写对应的低于有报错，比如华东-浙江2  或者华东-浙江  拼音，汉字，以及网上提供的简写都尝试了，都不行！

报错如下：

"app": "Crmeb",
                   "timestamp":"2023-07-07 23:22:27.145",
                   "level": "INFO",

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

根据网上所反馈七牛云配置华东区域的编码如下：

 Zone.zone0

问题：请问七牛云的所属地域应该怎么配？
