weavescope after installing on openshift cluster not showing container and process details.

[cynosure711]

Tried installing scope as mentioned in the https://cloud.weave.works/k8s/scope.yaml & also followed the additional commands mentioned in https://www.weave.works/docs/scope/latest/installing/#ose . But still, the error persists. Here are the logs for the weave-scope agent.

looks like there is still support issues with cri-o for container details, but the above yaml should get you more functionality.
