Rollover_alias XXX does not point to index XXX

[wajika]

Based on clues from other posts, I probably understand that I need to force the index to be associated with the alias.

The correct operation is similar to

POST _aliases
{
  "actions": [
    {
      "add": {
        "index": "apm-7.14.0-transaction-*",
        "alias": "apm-7.14.0-transaction"
      }
    }
  ]
}
