Logstash 5.2 not working with Kafka 9 and AVRO

I have installed Logstash 5.2.0 with logstash-input-kafka 4.1.1 and logstash-codec-avro 3.0.0 and trying to read data from Cloudera Kafka 9 but I am getting the gollowing error:

Same works well with Logstash 2.4 and logstash-codec-avro 2.0.4.

Here is my logstash config file:

input {
  kafka {
    bootstrap_servers => "server1:9092,server2:9092,server3:9092,server4:9092,server5:9092"
    topics => ["mytopicname"]
    group_id => "mygroup"
    codec => avro {
      schema_uri => "/apps/schema/rocana3.schema"
    }
  }
}
filter {
}
output {
        file {
          path => "/apps/elk/test/dump.txt"
        }
}

ArgumentError when using Kafka input Avro codec

The default serializer was changed in logstash 5 from byte array deserializer to string deserializer.

I simply added the following to my input > kafka and it worked.

key_deserializer_class => "org.apache.kafka.common.serialization.ByteArrayDeserializer"
value_deserializer_class => "org.apache.kafka.common.serialization.ByteArrayDeserializer"

input {
  kafka {
    bootstrap_servers => "server1:9092,server2:9092,server3:9092,server4:9092,server5:9092"
    topics => ["mytopicname"]
    group_id => "mygroup"
	key_deserializer_class => "org.apache.kafka.common.serialization.ByteArrayDeserializer"
    value_deserializer_class => "org.apache.kafka.common.serialization.ByteArrayDeserializer"
    codec => avro {
      schema_uri => "/apps/schema/rocana3.schema"
    }
  }
}
