I was trying to run a Spring boot Kafka Stream example from https://cloud.spring.io/spring-cloud-stream-binder-kafka/spring-cloud-stream-binder-kafka.html#_usage_2 site.
Am able to successfully build it. But while running it getting error as shown below (java.lang.IllegalStateException: Error processing condition on org.springframework.cloud.stream.function.FunctionConfiguration). Could anyone help to figure out the issue in the code?
ReplicateKafkaStreamApplication.java
