if this is a keystone bug, which by the sound of it, isn't likely, we would need some logs

Install an Ubuntu Openstack on a VM. 2. Login to the horizon for that VM. 3. Add a new user role using the following command using CLI: keystone user-role-add --user <AN_EXISTING_USER> --tenant <AN_EXISTING_TENANT> --role < MEMBER_ROLE> 4. Remove the user role, using the following command: keystone user-role-remove --user <SAME_EXISTING_USER> --tenant <SAME_EXISTING_TENANT> --role < SAME_MEMBER_ROLE> 5. Refresh the horizon, UI redirects to an error message page, with the following error message: "Something went wrong! An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator." A screenshot of the UI is attached. Please note that refreshing the page does not resolve the issue. However, either clearing the browser's cookies/history for that session or opening the horizon on an "Incognito" mode may resolve the issue.
