2.0.0

Reproduction steps

InputStream envAsStream = Thread.currentThread().getContextClassLoader().getResourceAsStream(".env");
Assert.assertNotNull(".env file not found in classpath", envAsStream);
Properties env = new Properties();
env.load(envAsStream);

String url = env.getProperty("elasticsearch.url");
String username = env.getProperty("elasticsearch.username");
String password = env.getProperty("elasticsearch.password");

BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(username, password));

RestClient restClient = RestClient.builder(HttpHost.create(url))
    .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider))
    .build();
RestClientTransport elasticsearchTransport = new RestClientTransport(restClient, new JacksonJsonpMapper());
ElasticsearchClient elasticsearchClient  = new ElasticsearchClient(elasticsearchTransport);
ElasticsearchIndicesClient indices = elasticsearchClient.indices();
GetIndexTemplateResponse indexTemplatesResponse = indices.getIndexTemplate(b-> b.name("logs-apm.app"));

Expected Results

The logs-apm.app index template, similar to the HTTP request GET /_index_template/logs-apm.app

Actual Results

co.elastic.clients.json.UnexpectedJsonEventException: Unexpected JSON event 'VALUE_TRUE' instead of '[KEY_NAME, VALUE_STRING]'

Move to later as we have implemented a workaround.

[cyrille-leclerc]

Workaround in place. Won't fix as we have limited contributions to integrate with Elastic at the moment.
