Running into exception while using cloudevent values in kafka streams

Beginne damit, das Java-Beispiel mit CloudEvents Kafka 2.5.0 und Kafka Streams 2.8.0 zu reproduzieren, und untersuche anschließend CloudEventSerializer sowie den im Stacktrace gezeigten Serialisierungspfad des Kafka Streams state-store. Ermittle, ob die gemeldete Serde-Konfiguration für die KTable und den Join unterstützt wird; abgeschlossen ist die Aufgabe, wenn eine bestätigte Lösung oder eine dokumentierte, getestete Änderung vorliegt.

I want to take join between a kafka stream and a ktable. The poc works fine with stream data. However, when I use CloudEvent, I keep running into some or other issue related to serialization.

Here is my code sample -

Map<String, Object> ceSerializerConfigs = new HashMap<>();
ceSerializerConfigs.put(ENCODING_CONFIG, Encoding.STRUCTURED);
ceSerializerConfigs.put(EVENT_FORMAT_CONFIG, JsonFormat.CONTENT_TYPE);

CloudEventSerializer serializer = new CloudEventSerializer();
serializer.configure(ceSerializerConfigs, false);

CloudEventDeserializer deserializer = new CloudEventDeserializer();
deserializer.configure(ceSerializerConfigs, false);
Serde<CloudEvent> cloudEventSerde = Serdes.serdeFrom(serializer, deserializer);
KStream<String, CloudEvent> kStream = builder.stream("stream-topic", Consumed.with(Serdes.String(), cloudEventSerde));
KTable<String, CloudEvent> kTable = builder.table("ktable-topic", Consumed.with(Serdes.String(), cloudEventSerde));
KStream<String, CloudEvent> joined = kStream
    .join(kTable, (left, right) -> CloudEventBuilder.v1().withId(left.getId().concat(right.getId())).build());
joined.to(output, Produced.with(Serdes.String(), eventsSerde));
KafkaStreams kafkaStreams = new KafkaStreams(builder.build(), streamProps);
kafkaStreams.start();

I also tried using WrapperSerde - Issue with configuring Serdes for Kafka Streams

However I keep running into exception -

Am I missing anything, any help from CloudEvent team is appreciated.
