ILM, conditions field is empty

Hi, team!

  1. I created an ILM
PUT _ilm/policy/120-days-default
{
  "policy": {
    "phases": {
      "hot": {
        "min_age": "0ms",
        "actions": {
          "rollover": {
            "max_primary_shard_size": "30gb",
            "max_age": "7d"
          }
        }
      },
      "warm": {
        "min_age": "14d",
        "actions": {
          "forcemerge": {
            "max_num_segments": 1
          },
          "shrink": {
            "number_of_shards": 1
          }
        }
      },
      "cold": {
        "min_age": "30d",
        "actions": {}
      },
      "delete": {
        "min_age": "120d",
        "actions": {
          "delete": {
            "delete_searchable_snapshot": true
          }
        }
      }
    },
    "_meta": {
      "managed": true
    }
  }
}
  1. Attached the index
{
  "indices" : {
    "my_index-000001" : {
      "index" : "my_index-000001",
      "managed" : true,
      "policy" : "120-days-default",
      "lifecycle_date_millis" : 1669129036430,
      "age" : "52.1m",
      "phase" : "hot",
      "phase_time_millis" : 1669130711445,
      "action" : "complete",
      "action_time_millis" : 1669130975655,
      "step" : "complete",
      "step_time_millis" : 1669130975655,
      "phase_execution" : {
        "policy" : "120-days-default",
        "phase_definition" : {
          "min_age" : "0ms",
          "actions" : {
            "rollover" : {
              "max_primary_shard_size" : "30gb",
              "max_age" : "7d"
            }
          }
        },
        "version" : 1,
        "modified_date_in_millis" : 1669130682750
      }
    }
  }
}
  1. Specified is_write_index: true
my_index-000001 : {
  "aliases": {
       "my_index" : {
           "is_write_index" : true
}
}
}

But when I run the check POST my_index/_rollover?dry_run, condition field is empty

{
   "acknowledged" : false,
   "shards_acknowledged" : false,
    "old_index" : "my_index-000001",
   "new_index" : "my_index-000002",
   "rolled_over" : false,
   "dry_run" : true,
   "conditions" : {}
}

Why is the conditions field empty? What did I miss?

Someone can help?

It looks like this is a bug of the 8.0.0 version of elastic or kbana, rollover is actually working out
