      "details": "...",
      "level": "warning",
      "url": "https://docs.elastic.co/..."
    }
  ],
  "indices": [
    {
      "message": "Index was created before 6.0",
      "details": "...",
      "index": "myIndex",
      "level": "critical",
      "reindex": true,

To fix indices with the reindex attribute, set to true using the Start or resume reindex API.
