What happened + What you expected to happen

I cloned the KubeRay GitHub repo and deploy the operator's configuration from my local file system.
use kubectl create -k default/
error: couldn't make loader for namespace.yaml: got file 'namespace.yaml', but '/root/ray/kuberay/ray-operator/config/default/namespace.yaml' must be a directory to be a root

Reproduction script

kubectl 1.20.9 and k8s cluster was deployed

Anything else

No response

I cannot reproduce this error. My commands are as follows.

> cd ray-operator/config

> kubectl create -k default

This issue kubernetes-sigs/kustomize#3812 might be helpful. In addition, you can also try to upgrade your kubectl. My version is as follows.

> kubectl version
Client Version: version.Info{Major:"1", Minor:"23", GitVersion:"v1.23.8", GitCommit:"a12b886b1da059e0190c54d09c5eab5219dd7acf", GitTreeState:"clean", BuildDate:"2022-06-16T05:57:43Z", GoVersion:"go1.17.11", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"24", GitVersion:"v1.24.0", GitCommit:"4ce5a8954017644c5420bae81d72b09b735c21f0", GitTreeState:"clean", BuildDate:"2022-05-19T15:39:43Z", GoVersion:"go1.18.1", Compiler:"gc", Platform:"linux/amd64"}

This issue is the same as "Installing KubeRay Operator failing", and it is solved by upgrading kubectl (#702). Closed this issue.
