I am trying to install spinnaker on my kubernetes cluster but while it was being installed it failed to create namespace on my cluster getting error.

ERROR Unexpected exception: io.fabric8.kubernetes.client.KubernetesClientException: Operation: >[list] for kind: [Pod] with name: [null] in namespace: [spinnaker] failed. - Failed to deploy Spinnaker.

Follow deployment process written on spinnaker official documentation.

Checked rbac policy for kubernetes, but I have full accesson my cluster
