Do you know if this error is happening because a misconfiguration or it’s normal:

11:52:28 [application-akka.actor.default-dispatcher-10670] WARN  o.p.o.profile.creator.TokenValidator - Preferred JWS algorithm: null not available. Using all metadata algorithms: [RS256]
11:52:29 [application-akka.actor.default-dispatcher-10670] ERROR auth.sso.oidc.OidcCallbackLogic - Unable to renew the session. The session store may not support this feature

I have configured SSO with Google

This second Error is unfortunately a red-herring bubbling up from a 3rd party library we use for helping with OIDC. It is expected, and you can safely ignore it.
