Your broker auto.create.topics.enable setting must be enabled. auto.create.topics.enable=true

If you have access to broker, you can verify by typing:

kafka-configs --bootstrap-server <server:port> --entity-type brokers --describe --all | grep "auto.create.topics.enable"

If broker auto.create.topics.enable setting is disabled, AllowAutoCreateTopics in the ProducerBuilder has no effect.

@chinmayiinjam Is this still an issue even after verifying what @RFPAlves suggested above? If so, please provide debug logs.
