Can´t use the ilm explain in elasticsearch-java

Elastic Stack Elasticsearch
1

Dear all,

I'm trying to use the ilm explain api in the elasticsearch-java client. When I run the following code, I got an error, which is described below. Could someone please help me on this?

My dependencies:

		<dependency>
			<groupId>co.elastic.clients</groupId>
			<artifactId>elasticsearch-java</artifactId>
			<version>8.13.2</version>
		</dependency>

		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-databind</artifactId>
			<version>2.17.0</version>
		</dependency>

Code:

final RestClient restClient = RestClient.builder(HttpHost.create("http://localhost:9200")).build();
final ElasticsearchTransport transport = new RestClientTransport(restClient, new JacksonJsonpMapper());
final ElasticsearchClient elasticsearchClient = new ElasticsearchClient(transport);

final ElasticsearchIlmClient ilmClient = elasticsearchClient.ilm();

final String indexName = "index_name";
final ExplainLifecycleResponse explainLifecycleResponse = ilmClient.explainLifecycle(b -> b.index(indexName));

When I run this code, I got the following error. It seems like it is related to the property "managed", which is a boolean in the result and it seems to expect a string.

Error:

Caused by: co.elastic.clients.json.UnexpectedJsonEventException: Unexpected JSON event 'VALUE_TRUE' instead of 'VALUE_STRING'
