Producer property warnings on consumer creation

[apeloquin-agilysys]

const kafka = new Kafka({
  kafkaJS: {
    brokers: ["localhost:9092"]
  }
});
const consumer = kafka.consumer({
  kafkaJS: {groupId: GROUP_ID}
});
await consumer.connect();

Results in the following log entries, even though I have clearly not specified retry.backoff.ms or retry.backoff.max.ms.

{
  message: '[thrd:app]: Configuration property retry.backoff.ms is a producer property and will be ignored by this consumer instance',
  fac: 'CONFWARN',
  timestamp: 1715289786815
}
