dashboard.rest_client.RequestException: User '(simplestreams bucket owner)' does not have any keys configured.

ceph-mgr-dashboard: 17.2.5-0ubuntu0.22.04.3 (quincy)

Ceph dashboard reveals Internal Server Error whenever the "simplestreams" bucket is opened. It can be said as an upstream issue but the simplestreams bucket and its user are created by glance-simplestreams-sync so it would be nice to avoid this obvious error in the user facing interface.
