Answer

I see you are new here. You should always include version information and full stack trace for questions like this.

Upgrade your broker to >= 2.4 or set the binder replication factor property.

See https://github.com/spring-cloud/spring-cloud-stream-binder-kafka/commit/4161f875ede0446ab1d485730c51e6a2c5baa37a

• Change default replication factor to -1

Binder now uses a default value of -1 for replication factor signaling the broker to use defaults. Users who are on Kafka brokers older than 2.4, need to set this to the previous default value of 1 used in the binder.

In either case, if there is an admin policy that requires replication factor > 1, then that value must be used instead.
