Hi, I'm using rancher with an RKE1 cluster which I've been using for many months. I recently upgraded the cluster to k8s 1.24.13 and started getting the following error when deploying using

kubectl apply -k ...

(using kustomize to deploy several manifests):

error: error validating "kustomization/juicy-staging": error validating data: the server has asked for the client to provide credentials; if you choose to ignore these errors, turn validation off with --validate=false

This seems to be a simple authentication issue, but I can execute any other kubectl command I can think of without issue, and the kustomize deployment even works if I add

--validate=false

. I'll add some more detail in a thread.
