> Per [KIP-289|https://cwiki.apache.org/confluence/display/KAFKA/KIP-289%3A+Improve+the+default+group+id+behavior+in+KafkaConsumer], the use of an empty value for {{group.id}} configuration was deprecated back in 2.2.0.
> In 3.7, the {{AsyncKafkaConsumer}} implementation will throw an error (see KAFKA-14438).
> This task is to update the {{LegacyKafkaConsumer}} implementation to throw an error in 4.0.
