mgr/dashboard: fix gateways section error:”404 - Not Found RGW Daemon not found: None”
A case was missed here where we do have a default realm created but no default_zonegorup, in that case, the existing behavior should prevail and that's not being handled. If a default_realm is created but no default_zonegroup is there, weshould continue getting the keys from daemon_name = next(iter(daemon_keys))
