Kafka Avro Deserialization Exception - apache-kafka

Question

I am using Avro maven plugin to autogenerate the schema for .avsc file. In my AVSC i have one field defined as
{
"name": "priceUSD",
"type": [
"null",
{
"type": "bytes",
"scale": 5,
"precision": 20,
"connect.version": 1,
"connect.parameters": {
"scale": "5",
"connect.decimal.precision": "20"
},
"connect.name": "org.apache.kafka.connect.data.Decimal",
"logicalType": "decimal"
}
],
"default": null
}
But when i am consuming the record i am getting "ClassCastException: java.math.BigDecimal cannot be cast to java.nio.ByteBuffer"
My application.yaml have configuration as below :
spring:
kafka:
producer:
value-serializer: io.confluent.kafka.serializers.KafkaAvroSerializer
key-serializer: io.confluent.kafka.serializers.KafkaAvroSerializer
bootstrap-servers: localhost:9092

consumer:

key-deserializer: org.springframework.kafka.support.serializer.ErrorHandlingDeserializer
value-deserializer: org.springframework.kafka.support.serializer.ErrorHandlingDeserializer

I have tried maven configuration with my plugin as below but that also doesn't seem to help
true
Please help me understand what i am missing here.
