Elasticsearch 8.9.1 template error

[smarakdas314]

Hi,
trying to set this up in
elasticsearch 8.9.1

Template creation I copy pasted is giving me an error, what I am missing ?

  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 1,
    "index.refresh_interval": "10s",
    "index.query.default_field": "groupLabels.alertname"
  },
  "mappings": {
    "_default_": {
      "_all": {
        "enabled": false
      },
      "properties": {
        "@timestamp": {
          "type": "date",
          "doc_values": true
        }
      },
      "dynamic_templates": [
        {
          "string_fields": {
            "match": "*",

            }
          }
        }
      ]
    }
  }
}
