Hi, while trying to use the Swan KeyCloakAuthenticator extension for a separate JupyterHub instance, I came across an error in KeyCloak that “?redirect_uri” for the logout endpoint is deprecated and should use “?post_logout_redirect_uri” plus either a token hint or the client ID instead (KeyCloakAuthenticator: 'redirect_uri' parameter is deprecated for post-logout redirect in Keycloak · Issue #125 · swan-cern/jupyterhub-extensions · GitHub)
I made a pull request already at KeyCloakAuthenticator: switch "redirect_uri" for "post_logout_redirect_uri" in logout config by jezwilkinson · Pull Request #126 · swan-cern/jupyterhub-extensions · GitHub that would address this (using the client_id in this case) - not sure if this is the right forum for it but I also don’t know if the jupyterhub-extensions repo is actively monitored, and maybe someone here knows who would be the right person to contact about it.
