使用springboot插入到elasticsearch数据流时抛出错误“只允许在数据流中使用op_type为create的写操作”

import org.elasticsearch.action.index.IndexRequest;

@Service
public class ElasticsearchService {

    @Autowired
    private RestHighLevelClient client;

    public void insertData() {
        IndexRequest request = new IndexRequest("index_name");
        request.id("document_id");
        request.source("{\"field1\":\"value1\",\"field2\":\"value2\"}", XContentType.JSON);

        try {
            IndexResponse response = client.index(request, RequestOptions.DEFAULT);
            System.out.println("插入成功：" + response.getResult().toString());
        } catch (Exception e) {
