【Flink】RuntimeException: Row arity of from does not match serializers

1.美图

2.背景

ControlEvent继承Row，想跟着flink的算子往下传递，结果报错

import org.apache.flink.types.Row;

public class  ControlEvent extends Row {
    private String id;
    private String name;

    public ControlEvent() {
        super(1);
    }

    public ControlEvent(String id, String name) {
        // 1
        super(1);
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

报错如下

测试类参考：org.apache.flink.streaming.examples.rowserializer.RowSerializerDemoTest#testRowSerializer1

	@Test
    public void testRowSerializer1() {
        TypeInformation<Row> typeInfo = new RowTypeInfo(
                BasicTypeInfo.INT_TYPE_INFO,
                BasicTypeInfo.STRING_TYPE_INFO);
        Row row1 = new Row(2);
        row1.setField(0, 1);
        row1.setField(1, "a");

        ControlEvent controlEvent = new  ControlEvent();
        controlEvent.setId("1");
        controlEvent.setName("lcc");
        Row row2 = Row.of(controlEvent);

        TypeSerializer<Row> serializer = typeInfo.createSerializer(new ExecutionConfig());
        RowSerializerTestInstance instance = new RowSerializerTestInstance(serializer, row1, row2);
        instance.testAll();
    }
