I am getting this exception looged for every one of my Junit 5 Tests in a Spring Boot 2.5 project using org.springframework.cloud:spring-cloud-starter-kubernetes-client-config. I use local yaml property files for tests, not Kubernetes anywhere.

I wonder if it is just because I run the tests locally (not in Kubernetes) or if is a real problema that will arise when I deploy in Kubernetes (and try to read the configuration from Kubernetes ConfigMaps)
