Caused by: java.lang.ClassNotFoundException: org.apache.kafka.common.Configurable

This error message indicates that the Java class "org.apache.kafka.common.Configurable" could not be found. This could be due to one of several reasons:

1. The required Kafka library or dependency is not included in the project or application.
2. The Kafka library or dependency is not properly configured or installed.
3. The classpath is not set up correctly to include the required Kafka library or dependency.

To fix this error, you should ensure that the Kafka library or dependency is properly configured and included in the project or application. You should also check the classpath to ensure that it includes the required Kafka library or dependency. If you are using a build tool like Maven or Gradle, you can check the dependencies in the project configuration file to ensure that the required Kafka library or dependency is included.
