3.3.4版本olap表生成列报错

[aaaaaaaaaaaaa]

【详述】我们从3.2版本的集群迁移到3.3.4版本，从3.2复制的ddl到3.3.4会自动更新

3.2 DDL

CREATE TABLE `instance` (
  `id` varchar(1048576) NOT NULL COMMENT "主键",
  `start_time` datetime NULL COMMENT "",
  `end_time` datetime NULL COMMENT "任务结束时间",
  `status` int(11) NULL DEFAULT "1" COMMENT "记录状态,默认1",
  `remark` varchar(1048576) NULL COMMENT "任务备注",
  `create_time` datetime NULL DEFAULT CURRENT_TIMESTAMP COMMENT "任务创建时间",
  `update_time` datetime NULL DEFAULT CURRENT_TIMESTAMP COMMENT "任务最后更新时间",
  `sync_time` double NULL AS timestampdiff(SECOND, start_time, end_time) / 60 COMMENT "实例执行时长"
) ENGINE=OLAP 
PRIMARY KEY(`id`)
COMMENT "实例"
DISTRIBUTED BY HASH(`id`) BUCKETS 10 
PROPERTIES (
"replication_num" = "3",
"in_memory" = "false",
"enable_persistent_index" = "false",
"replicated_storage" = "true",
"compression" = "LZ4"
);`

3.3.4 DDL

CREATE TABLE `instance` (
  `id` varchar(1048576) NOT NULL COMMENT "主键",
  `start_time` datetime NULL COMMENT "开始同步数据时间",
  `end_time` datetime NULL COMMENT "任务结束时间",
  `status` int(11) NULL DEFAULT "1" COMMENT "记录状态,默认1",
  `remark` varchar(1048576) NULL COMMENT "任务备注",
  `create_time` datetime NULL DEFAULT CURRENT_TIMESTAMP COMMENT "任务创建时间",
  `update_time` datetime NULL DEFAULT CURRENT_TIMESTAMP COMMENT "任务最后更新时间"
) ENGINE=OLAP 
PRIMARY KEY(`id`)
COMMENT "实例"
DISTRIBUTED BY HASH(`id`) BUCKETS 10 
PROPERTIES (
"compression" = "LZ4",
"datacache.enable" = "true",
"enable_async_write_back" = "false",
"enable_persistent_index" = "false",
"replication_num" = "3",
"storage_volume" = "def_volume"
);

我需要在3.3.4版本中增加生成列 sync_time
执行SQL
ALTER TABLE config.instance
ADD COLUMN sync_time double AS timestampdiff(SECOND, start_time, end_time) / 60
报错，报错信息为
Detail message: Generated Column only support olap table.

【StarRocks版本】例如：3.3.4
