Spring Cloud Config Spring Config Server - Kubernetes Service Account auth not working

Description:

Spring Boot Version: 3.0.5

Spring Cloud Version: 2022.0.1

Kubernetes Service Account-based authentication doesn't work even when all the corresponding properties are specified.

Can some help with this issue? Am I missing anything here?
