2 aliases (read, write) per index pattern with rollover

Elastic Stack Elasticsearch

Hello hello, good morning and happy Wednesday!

May I ask your help and also if this is a common/known issue?

This is a production cluster, ES 8.8.0. I am doing tests with a 5min rollover.

Due to the nature of our application we need 2 aliases per index pattern:
$indexName_read
$indexName_write

The rollover fails, and to make it work we need to remove the aliases from the index_template (both of them). Then, the rollover works, the new index is created ONLY with the alias: "%indexName_write".

I came to the understanding that I need to manually add the other alias "$indexName_read" to the new index, is that the only solution? If yes, any suggestion on how to do it or will I have to add it as a feature to my application?

My lead index:

PUT rome_index-000001
{
  "aliases": {
    "rome_alias_read": {},
    "rome_alias_write": {
      "is_write_index": true
    }
  }
}

My index_template:

PUT _index_template/rome_template
{
  "index_patterns": ["rome_index-*"],
  "template": {
    "settings": {
      "index.lifecycle.name": "rome_ilm",
      "index.lifecycle.rollover_alias": "rome_alias_write",
      "number_of_shards": 3,
      "number_of_replicas": 1
    },
    "aliases": {
      "rome_alias_read": {},
      "rome_alias_write": {
        "is_write_index": true
      }
    }
  }
}

My ILM:

PUT _ilm/policy/rome_ilm
{
  "policy": {
    "phases": {
      "hot": {
        "min_age": "0ms",
        "actions": {
          "rollover": {
            "max_age": "5m"
          },
          "set_priority": {
            "priority": 100
          }
        }
      }
    }
  }
}

Rollover error:

"reason": "Rollover alias [rome_alias_write] can point to multiple indices, found duplicated alias [[rome_alias_write, rome_alias_read]] in index template [rome_template]"

This is the original topic I found, but without an apparent solution:
