On OpenShift 4.15 and greater, web terminals cannot be created when logged into the cluster as kubeadmin. The web terminal interface will display the following error message upon terminal creation: "Error Loading OpenShift command line terminal: User is not a owner of the requested workspace"

Regular users are not affected by this bug.

This affects all versions of Web Terminal when installed on an OpenShift 4.15 or greater cluster.

This bug stems from a change in the OpenShift console. which I have reported here: https://github.com/openshift/console/issues/13696
