I'm preparing to upgrade spring-boot 3.2.0 and spring-cloud 2023.0.0 for my preview demo, which is a demo abou spring-cloud-stream-binder-kafka and spring-cloud-stream-binder-kafka-streams. Here it's my demo. https://github.com/SingKS8/kafka-stream-demo

I updated spring-boot from 3.1.5 to 3.2.0-RC2, and spring-cloud from 2022.0.4 to 2023.0.0-RC1 (spring cloud stream 4.1.0-RC1).
I find that if I use a @Configuration or @Component class to define beans for functions about ktable or kstream, like the code UserFunction in my demo, I would get this exception.

And the instresting thing is that if I move the code in @Configuration class to @SpringBootApplication class, like "spring-tips" done, I won't get this issue.

My original demo is spring-boot 3.1.5 and spring-cloud 2022.0.4, and it is running successfully, So you cloud downgrade my demo dependencies to debug what is different.
