kafka-avro-console-consumer引发KafkaException：SyncGroup中发生意外错误

Question

我正在对应该包含几条记录的测试主题进行简单的控制台使用者查询。仅供参考，我最近删除了该主题，然后调用了REST服务以在那里产生记录，从而重新创建了该主题。

这与运行Apache Kafka 2.0.1的Confluent平台5.0.1一起使用。

谷歌搜索此错误，我可以看到https://issues.apache.org/jira/browse/KAFKA-6631，它具有相同的错误，但是我根本没有使用Streams。我目前的用法很简单。

sudo /usr/bin/kafka-avro-console-consumer --bootstrap-server localhost:9092 --topic metric-api-events-test --from-beginning
