Fatal error after logging in: Session name cannot be changed when a session is active

[n1tr0-5urf3r]

Hi all,

I configured the new icinga-sso-web module to use our Authentik provider. Here is the config:

After logging in and going through the OIDC flow, I end up with this error:

Any idea?

Edit: I logged out of all previous sessions and also tested it in a private window to rule out any local storage / session / cookie issues.

Edit2: I think I just found the issue: I had the wrong REDIRECT URI, since I was migrating from the RISE-GmbH module. Still, I think having an incorrect redirect URI shouldnt lead to a plain php error message.
