ob版本号：4.6.0.0 CE
obproxy版本号:4.3.6.1
遇到问题:
使用ALTER SYSTEM BACKUP TENANT='obmysql’进行备份时，报 -9120(cannot find object on object storage)。
已尝试措施:
1、使用S3://和OSS://，均报此错误。
2、file://尝试过，但改不成这个格式，报MySQL [(none)]> ALTER SYSTEM SET data_backup_dest=‘file:///data/backup_test_20260624’ TENANT=‘obmysql’;
ERROR 9120 (HY000): cannot find object on object storage
3、ob4.3.5.5可以正常备份
已经查询了官网、社区、大模型，未解决。故发帖求助，有偿
