我有一个Spring Boot 3.0.0 API，我正尝试将其与ElasticSearchJava客户端版本8.5.1集成
对于上下文，我在www.example.com上运行ElasticSearchelastic.co
每当我尝试运行搜索或索引文档时，都会出现以下错误：

在elastic上，我通过PUT请求为索引创建了索引，并确认了它的创建。
下面是我用来连接到ES的代码：

package com.poc.es.elasticsearchspringboot.config;

import co.elastic.clients.elasticsearch.ElasticsearchClient;
import co.elastic.clients.json.jackson.JacksonJsonpMapper;
import co.elastic.clients.transport.ElasticsearchTransport;
import co.elastic.clients.transport.rest_client.RestClientTransport;
import lombok.Getter;
import lombok.Setter;
import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.nio.client.HttpAsyncClientBuilder;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestClientBuilder;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@Getter
@Setter
public class ESRestClient {

    private String hostName = "https://xxxxxxx.gcp.cloud.es.io";
    private int port = 9243;
    private String username = "elastic";
    private String password = "xxxxxxxxxxx";

    @Bean
    public ElasticsearchClient getElasticSearchClient() {

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

        RestClientBuilder builder = RestClient.builder(new HttpHost(hostName, port, "https"))
                .setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder
                        .setConnectTimeout(5000)
                        .setSocketTimeout(60000))
                .setHttpClientConfigCallback(httpClientBuilder ->
                        httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider))
                ;

        // Create the low-level client
        RestClient restClient = builder.build();

        // Create the transport with a Jackson mapper
        ElasticsearchTransport transport = new RestClientTransport(restClient, new JacksonJsonpMapper());

        // And create the API client
        return new ElasticsearchClient(transport);
    }
}

下面是一些生成上述错误的搜索请求示例：

有谁能给我指个方向吗？

将DynamicMapping值序列化为布尔值而不是字符串。
将具有true/false值的枚举作为布尔值处理。
