Non String Key Deserialisers not working correctly with Kafka Input Plugin

[rkpundhir90]

Logstash information:

Logstash Version - 7.13.1

Run from Logstash windows zip version

Command - bin\logstash.bat -f config\logstash.conf

JVM (e.g. java -version):
AdoptOpenJDK 11.0.8

Description of the problem including expected versus actual behavior:

PFB Kafka input configuration with the schema registry url that stores the avro schema. When population the deserialiser class for key_deserializer_class to non string deserialiser ie .KafkaAvroDeserializer, logstash is producing the errors

kafka {
id => ""
bootstrap_servers => "localhost:9092"
topics => ["test-topics"]
client_id => "kafka-consumer"
group_id => "test"
auto_offset_reset => "earliest"
decorate_events => true
security_protocol => "SSL"
ssl_keystore_location => "keystore.jks"
ssl_keystore_password => "prmcert"
ssl_truststore_location => "truststore.jks"
ssl_truststore_password => "prmcert"
key_deserializer_class => "io.confluent.kafka.serializers.KafkaAvroDeserializer"
schema_registry_url => "http://localhost:9093"
}
