when trying to logout from Discourse 500 server error

Created by: radumalica

All good, configured SSO on Discourse side (latest version of Discourse), enable sso = on, secret and API details inserted into local.py, i checked everything twice, admin username, keys/secrets.

I login to AAuth with random Eve character, go to Services, go to forums. I get authenticated to Discourse properly with my ticker and char name as it should

When i click logout of discourse, nothing happens, it just refreshes the page fast and i am still logged in.

I go back to AAuth, login as admin, go to forums, still the other user appears as logged in. When i click logout, i get 500 Internal Server Error:
