Has anyone recently configured an OIDC auth provider for HedgeDoc?

[gh0stface]

I have configured HedgeDoc to not use Cloudron for auth and configured an OAuth2 provider, but nothing is working.

I tried using Amazon Cognito and Nextcloud. Each of these are throwing an "Internal Server Error" and the logs aren't meaningful to me.

I'm very knowledge with authN/authZ systems, but the blackbox here for me is HedgeDoc. It almost feels like it's not properly calling the /token endpoint of the IdP correctly. Essentially throwing a 500 error.

I followed the instructions here for configuring OAuth2: https://docs.hedgedoc.org/guides/auth/nextcloud/.

I was able to configure using GitHub without an issue following this: https://docs.hedgedoc.org/guides/auth/github/. But, I have no access control (authZ) using GitHub, anyone would be able to sign-in.

Has anyone configured this to use either an OIDC or OAuth2 provider successfully? I did read this post, but this was not helpful for me.
