Using:

```auto
<dependency>
        <groupId>co.elastic.clients</groupId>
        <artifactId>elasticsearch-java</artifactId>
        <version>8.13.4</version>
</dependency>

```

When executing something like:

```auto
CreateIndexRequest createIndexRequest = CreateIndexRequest.of(b -> b
         .index(indexName)
         .withJson(input)
);
CreateIndexResponse response = elasticsearchAsyncClient.indices().create(createIndexRequest).get();

```

Where input contains an elasticsearch schema that utilizes dynamic templates with path\_match where its value is an array like:

```auto
{
  "settings": {
    // Some settings
  },
  "mappings": {
    "dynamic": "strict",
    "dynamic_templates": [
      {
        "some_template": {
          "path_match": [
            "some_field",
            "some_other_field"
          ],
          "mapping": {
          }
        }
      }
    ],
    "properties": {
      // Some properties
    }
  }
}

```

Is failing with error:

```auto
co.elastic.clients.json.JsonpMappingException: Error deserializing co.elastic.clients.elasticsearch._types.mapping.DynamicTemplate: co.elastic.clients.json.UnexpectedJsonEventException: Unexpected JSON event 'START_ARRAY' instead of '[KEY_NAME, VALUE_STRING, VALUE_NUMBER, VALUE_TRUE, VALUE_FALSE]'

```

Hello!  
This is a know issue, the client still needs to allow arrays instead of just strings for Dynamic Templates. You can follow our progress on this issue [here](https://github.com/elastic/elasticsearch-java/issues/648).
