I use spring-cloud-stream-binder-kafka to connect to the kafka broker
I updated spring-cloud-dependencies version to 2021.0.1
I went from this
[INFO] +- org.springframework.cloud:spring-cloud-stream-binder-kafka:jar:3.0.11.RELEASE:compile
[INFO] | +- org.springframework.cloud:spring-cloud-stream-binder-kafka-core:jar:3.0.11.RELEASE:compile

[INFO] | +- org.apache.kafka:kafka-clients:jar:2.5.1:compile
[INFO] | \- org.springframework.kafka:spring-kafka:jar:2.5.11.RELEASE:compile
To this
[INFO] +- org.springframework.cloud:spring-cloud-stream-binder-kafka:jar:3.2.2:compile
[INFO] | +- org.springframework.cloud:spring-cloud-stream-binder-kafka-core:jar:3.2.2:compile

[INFO] | +- org.apache.kafka:kafka-clients:jar:3.0.1:compile
[INFO] | \- org.springframework.kafka:spring-kafka:jar:2.8.4:compile
Before the update everything worked fine, I consume JSON array message ([{}]) from topic (each message is an JSON array) and using ObjectMapper I convert Message<String> to a POJO List
@Bean
public Function<Message<String>, Message<Map<String, Object>>> process(HandleMessage handleMessage) {
return message -> handleMessage.onMessage(message);
}
But now after the update when it try to consume messages I got these exceptions :
Caused by: org.apache.kafka.common.errors.SerializationException: Can't convert value of class java.lang.String to class org.apache.kafka.common.serialization.ByteArraySerializer specified in value.serializer
Caused by: java.lang.ClassCastException: class java.lang.String cannot be cast to class [B (java.lang.String and [B are in module java.base of loader 'bootstrap')
Caused by: org.apache.kafka.common.errors.SerializationException: Can't convert value of class reactor.core.publisher.FluxMapFuseable to class org.apache.kafka.common.serialization.ByteArraySerializer specified in value.serializer
Caused by: java.lang.ClassCastException: class reactor.core.publisher.FluxMapFuseable cannot be cast to class [B (reactor.core.publisher.FluxMapFuseable is in unnamed module of loader 'app'; [B is in module java.base of loader 'bootstrap')
There the complete stacktrace :
org.springframework.messaging.MessageHandlingException: error occurred in message handler [org.springframework.cloud.stream.binder.kafka.KafkaMessageChannelBinder$ProducerConfigurationMessageHandler@8ff35b3]; nested exception is org.apache.kafka.common.errors.SerializationException: Can't convert value of class java.lang.String to class org.apache.kafka.common.serialization.ByteArraySerializer specified in value.serializer

I have checked some Spring Cloud code source and especially this class org.springframework.cloud.function.context.catalog.SimpleFunctionRegistry and i have found out that this method is added fluxifyInputIfNecessary, I guess some streaming is happening, the message is converted to be send as an FluxMapFuseable
and why the process function is not even called ? because the error is occuring in the producer level
So any idea to how solve this problem ?
