Don't ask the same question in multiple places; it's a waste of your time and ours.

I already answered you on GitHub.

I just tested your yaml with Boot 2.1.15 and Greenwich.SR6 (and Boot 2.2.8/Hoxton.SR5) and it works just fine. The only changes I made was to change the binding name to input and comment out the avro stuff.

@SpringBootApplication
@EnableBinding(Sink.class)
public class Kbgh9181Application {

    public static void main(String[] args) {
        SpringApplication.run(Kbgh9181Application.class, args);
    }

    @StreamListener(Sink.INPUT)
    public void listen(String in) {
        throw new RuntimeException("foo");
    }

    @KafkaListener(id = "kbgh918", topics = "dead-out", properties = "auto.offset.reset:earliest")
    public void listen(Message<?> in) {
        System.out.println(in);
    }

}

GenericMessage [payload=byte[3], headers={x-original-offset=[B@67917b81, x-original-partition=[B@467895cd, kafka_timestampType=CREATE_TIME, kafka_receivedMessageKey=null, kafka_receivedTopic=dead-out, kafka_offset=5, x-exception-message=[B@51def01e, x-exception-fqcn=[B@531d42e5, kafka_consumer=org.apache.kafka.clients.consumer.KafkaConsumer@3fbc6674, x-original-topic=[B@3d684ab3, x-original-timestamp-type=[B@1b101300, kafka_receivedPartitionId=0, x-original-timestamp=[B@222370ed, kafka_receivedTimestamp=1592402977606, x-exception-stacktrace=[B@7e703d1b}]
