      * Previously, a regression was introduced causing the *Cluster Settings* page to return an error when a ClusterVersion’s `status.availableUpdates` had a value of `null` and `Upgradeable=False`. With this update, `status.availableUpdates` are allowed to have a `null` value. (link:https://issues.redhat.com/browse/OCPBUGS-6053[*OCPBUGS-6053*])

      Description of problem:

      When a ClusterVersion's `status.availableUpdates` has a value of `null` and `Upgradeable=False`, a run time error occurs on the Cluster Settings page as the UpdatesGraph component expects `status.availableUpdates` to have a non-empty value.

      Steps to Reproduce:

      1.  Add the following overrides to ClusterVersion config (/k8s/cluster/config.openshift.io~v1~ClusterVersion/version)

spec:
  overrides:
    - group: apps
      kind: Deployment
      name: console-operator
      namespace: openshift-console-operator
      unmanaged: true    
    - group: rbac.authorization.k8s.io
      kind: ClusterRole
      name: console-operator
      namespace: ''
      unmanaged: true
2.  Visit /settings/cluster and note the run-time error (see attached screenshot)

      Actual results:

      An error occurs.

      Expected results:

      The contents of the Cluster Settings page render.
