Если ли универсальный тип в elasticSearch?

Хочу создать документ, где поле request и response может принимать любой тип (Object, String, Integer, null)
но при маппинге ругается:

: Elasticsearch exception [type=illegal_argument_exception, reason=Can't merge a non object mapping [request] with an object mapping [request]]

Вопрос, как можно это реализовать?
Код:

@Data
@Accessors(chain = true)
@Document(indexName = "backoffice-action")
public class ExtendedBackofficeActionEntity {

    @Id
    private String id;

    @Field(type = FieldType.Text)
    private String serviceName;

    @Field(type = FieldType.Text)
    private String userName;

    @Field(type = FieldType.Keyword)
    private String login;

    @Field(type = FieldType.Keyword)
    private String requestPath;

    @Field(type = FieldType.Keyword)
    private String requestMethod;

    @Field(type = FieldType.Text)
    private String queryParams;

    @Field(type = FieldType.Keyword)
    private String requestId;

    @Field(type = FieldType.Object)
    private Object request;

    @Field(type = FieldType.Object)
    private Object response;

    @Field(type = FieldType.Date, name = "@timestamp")
    private Instant requestedAt;

    @Field(type = FieldType.Integer)
    private Integer responseStatus;

    @Transient
    private boolean isValid;

}

@PostConstruct
    public void configureIndices() {
        var indexName = logProperties.getIndex().getExtendedBackofficeAction();
        if (!elasticsearchOperations.indexExists(indexName)) {
            createIndex(indexName);
        }
    }

    private void createIndex(String indexName){
        var settings = new HashMap<String, Object>();
        settings.put(INDEX_NUMBER_OF_SHARDS, logProperties.getExtendedBackofficeActionShards());
        settings.put(INDEX_NUMBER_OF_REPLICAS, logProperties.getExtendedBackofficeActionReplicas());

        elasticsearchOperations.createIndex(indexName, settings);
        elasticsearchOperations.putMapping(ExtendedBackofficeActionEntity.class, getDynamicTemplateMapping());
    }

    // Create dynamic type template for request and response fields (ExtendedBackofficeActionEntity)
    private Map<String, Object> getDynamicTemplateMapping() {
        Map<String, Object> dynamicTemplate = new HashMap<>();
        dynamicTemplate.put("dynamic_templates", List.of(
                Map.of(
                        "request_response_fields", Map.of(
                                "path_match", "request|response",
                                "mapping", Map.of(
                                        "type", "object",
                                        "dynamic", true
                                )
                        )
                )
        ));

        return dynamicTemplate;
    }
