通过Flink-doris-connector Flink查询doris表数据报错

版本信息：
Flink：1.18.1
Git : file://VM-10-14-centos@Unknown
Version : doris-2.0.0-alpha1
BuildInfo : VM-10-14-centos
BuildTime : Mon, 01 May 2023 15:05:04 UTC
Flink-doris-connector: flink-doris-connector-1.18:1.5.2

代码：官网提供的代码，port设置为9031（9031:9030），doris通过docker部署，fe和be在同一个服务器上。

StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
DorisOptions.Builder builder = DorisOptions.builder()
        .setFenodes("FE_IP:9031")
        .setTableIdentifier("demo.orders")
        .setUsername("root")
        .setPassword("");

DorisSource<List<?>> dorisSource = DorisSourceBuilder.<List<?>>builder()
        .setDorisOptions(builder.build())
        .setDorisReadOptions(DorisReadOptions.builder().build())
        .setDeserializer(new SimpleListDeserializationSchema())
        .build();

env.fromSource(dorisSource, WatermarkStrategy.noWatermarks(), "doris source").print();

报错信息：

通过pymysql可以正常查询数据

补充docker yaml文件信息，需要提前创建docker网络：docker network create --driver bridge --subnet=xx.xx.xx.0/24 doris-network
