Exception: "Could not encode record with given Schema" when using AvroSchemaSerializer

[1sumitkumar]

I am new to Laravel and Kafka. I am doing a poc on Kafka with Avro. I am able to implement this with JsonSchema but when I am trying to implement Avro Serializer and deserializer I am facing this issue. Can anyone please help !

I am using https://github.com/confluentinc/cp-all-in-one/blob/7.5.0-post/cp-all-in-one/docker-compose.yml with Laravel.

  $topic = 'test-topic';
  $version = 1;
  $subject = $topic . '-value';
    $cachedRegistry = new CachedRegistry(
        new BlockingRegistry(
            new PromisingRegistry(
                new Client(['base_uri' => 'schema-registry:8081'])
            )
        ),
        new AvroObjectCacheAdapter()
    );

    $registry = new AvroSchemaRegistry($cachedRegistry);
    $recordSerializer = new RecordSerializer($cachedRegistry,  [
        // If you want to auto-register missing schemas set this to true
        RecordSerializer::OPTION_REGISTER_MISSING_SCHEMAS => false,
        // If you want to auto-register missing subjects set this to true
        RecordSerializer::OPTION_REGISTER_MISSING_SUBJECTS => true,
    ]);

    $registry->addBodySchemaMappingForTopic(
        $topic,
        new \Junges\Kafka\Message\KafkaAvroSchema($subject, $version , $parsedSchema)

    $producer = Kafka::publishOn('test-topic')->withDebugEnabled()->usingSerializer($serializer);
    $producer->send();`
    die();
