I clicked to open on hosted CRW, the url is https://workspaces.openshift.com/#https://github.com/apupier/fuse-rest-http-booster/tree/v7.8.0-redhat-sb2-branch-DevWorkspaceAction

I was proposed to restart workspace, i click to restart it.
Then i wanted to add another extensuion and clicked on View -> Plugins and got a notification error:
