我编写了以下函数并得到如下所示的响应：

  public async Task<GetMappingResponse> ShowMapping(string indexname)
        {
            var result =await _client.Indices.GetMappingAsync(new GetMappingRequest(indexname));
            return result;
        }

启动 Kibana 7.5 时出现致命错误，我没有配置任何内容，我只是运行 elasticsearch.bat（也是 v7.5）和 kibana.bat

'{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"No handler for type [flattened] declared on field [state]"}],"type":"mapper_parsing_exception",
"reason":"Failed to parse mapping [_doc]: No handler for type [flattened] declared on field [state]",
"caused_by":{"type":"mapper_parsing_exception","reason":"No handler for type [flattened] declared on field [state]"}},"status":400}'

我还可以启动 kibana 6.8.5，但无法连接到我的 elasticsearch 节点。
