I'm using Elasticsearch 8.6.2 version with spring boot 2.7.12 for doing a CRUD application over an index in elasticsearch.

Configuration class:

@Configuration
public class ConfigElasticSearch {

  @Value("${elasticsearch.url}")
  private String urlElasticsearch;

  @Value("${elasticsearch.user}")
  private String userElasticsearch;

  @Value("${elasticsearch.pwd}")
  private String pwdElasticsearch;

  @Bean
  public RestHighLevelClient client() {
    ClientConfiguration clientConfiguration = ClientConfiguration.builder()
        .connectedTo(urlElasticsearch)
        .withBasicAuth(userElasticsearch, pwdElasticsearch)
        .build();
    return RestClients.create(clientConfiguration).rest();
  }

  @Bean
  public ElasticsearchOperations elasticsearchTemplate() {
    return new ElasticsearchRestTemplate(client());
  }
}

I have my entity class:

@Document(indexName = "empleadosindex", shards = 1, replicas = 0)
public class EmpleadoEntity {

  public EmpleadoEntity() {
    super();
  }

  @Id
  private String id;

  @Field(type = FieldType.Text, name = "dni")
  private String dni;

  @Field(type = FieldType.Text, name = "nombre")
  private String nombre;

  @Field(type = FieldType.Long, name = "telefono")
  private Long telefono;

Also, my interface for spring-data:

@Repository
public interface EmpleadoRepository extends ElasticsearchRepository<EmpleadoEntity, 
String> {
}

My pom is using spring boot starter 2.7.12, with this dependency for elasticsearch:

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

If I execute findById() or findAll(), it works and returns the proper information stored in elasticsearch.

But if I execute save(entity), it fails returning an exception, but the content of the document is stored in elastisearch.

The error that I got is:

    org.springframework.dao.DataAccessResourceFailureException: Unable to parse 
response body for Response{requestLine=POST /clientindex/_doc?timeout=1m HTTP/1.1, 
host=http://localhost:9200, response=HTTP/1.1 201 Created}; nested exception is

Can anyone help me to discover why is happening this error when reading response from elasticsearch when calling to save() method?

Thank you in advance!

Best regards!

See my answer at https://stackoverflow.com/a/76396961/4393565

Do you set the Elasticsearch compatibility headers in your requests? This error normally is seen when The Elasticsearch 8 server sends an answer in a format not understood by the 7 client (and setting the headers does not guarantee it's working).

The best thing is to either stay on Boot 2.7 and use an Elasticsearch 7 instance, or upgrade to the current version of Spring Boot - or at least to 3.0

Thank you @PJ.Meisch! I have set headers and it works fine:

 HttpHeaders compatibilityHeaders = new HttpHeaders();
  compatibilityHeaders.add("Accept", "application/vnd.elasticsearch+json;compatible-with=7");
  compatibilityHeaders.add("Content-Type", "application/vnd.elasticsearch+json;" + "compatible-with=7");
