com.fasterxml.jackson.databind.exc.MismatchedInputException - while configuring Kubernetes config server into spring-boot api

Question

I am trying to configure spring-cloud-starter-Kubernetes-config as config server and trying to have my springboot 3 api to act as a client to it. I have added the config into application.yml and also added the dependencies into pom.xml. But I am getting a persistent error related to Jackson databind dependency.

Error Log: 03:15:50.781 [main] ERROR org.springframework.boot.SpringApplication -- Application run failed java.lang.IllegalArgumentException: Cannot construct instance of

I tried to exclude the Jacson libraries from Kubernetes dependencies and added the latest Jackson core dependencies but it still doesn't work.

Addition in pom:
