我正在使用具有kafka源和avro格式的flink sql客户端，配置如下：
[^a-zA-Z]表“事件”已成功创建，但是当我运行tables:
- name: event # name the new table
type: source # declare if the table should be "source", "sink", or "both"
# declare the external system to connect to
connector:
type: kafka
version: "universal"
topic: event
startup-mode: latest-offset
properties:
zookeeper.connect: localhost:2181
bootstrap.servers: localhost:9092
group.id: testgroup
# declare a format for this system
format:
type: avro
record-class: "org.flink.event"
# declare the schema of the table
schema:
- name: fields
data-type: ROW<`id` BIGINT,`time` BIGINT>
时出现错误：
select * from event;
kafka主题除“字段”外还有更多列，但我只想首先尝试一列。
