Hi@akhtar,
You need to update your cluster details to kubeconfig file. You can use the below-given command to update your cluster details.
$ kubectl config --kubeconfig=config-demo set-cluster development --server=URL --certificate-authority=fake-ca-file
$ kubectl config --kubeconfig=config-demo set-cluster scratch --server=https:URL --insecure-skip-tls-verify
I hope this will solve your error.
