Domain has been created successfully & kubectl get pods -n sample-domain1-ns is not returning any pods. While checking , receiving below error in the operator logs. Please guide me how to proceed further.

Are you testing against Kubernetes 1.25? If so, then this version of Kubernetes is not yet supported. It will be supported in the next release.

If not, then please respond with some more details about the Kubernetes environment that you are using.

Thanks a lot Ryan for your prompt response .

Yes, I tried with K8S 1.25. Now I have downgraded to 1.23 & it works fine.
