Terraform for_每个问题的数据类型

我有下一个代码将快照策略附加到特定实例的现有磁盘:

data "alicloud_ecs_disks" "db_disks" {
  instance_id = alicloud_instance.db.id
}

resource "alicloud_ecs_auto_snapshot_policy" "common" {
...
}

resource "alicloud_ecs_auto_snapshot_policy_attachment" "db" {
  for_each                = { for disk in data.alicloud_ecs_disks.db_disks.disks : disk.disk_id => disk }
  auto_snapshot_policy_id = alicloud_ecs_auto_snapshot_policy.common.id
  disk_id                 = each.key
}

当我运行计划时,它运行得很好,但在应用下一个计划后,由于错误而失败:

data.alicloud_ecs_disks.db_disks.disks is a list of object, known only after apply
│ 
│ The "for_each" value depends on resource attributes that cannot be
│ determined until apply, so Terraform cannot predict how many instances will
│ be created. To work around this, use the -target argument to first apply
│ only the resources that the for_each depends on.

解决这个问题的最佳选择是什么?它在某些机器上使用plan工作,有时不工作。谢谢
