OpenUnison Server error when forward-auth0 requests access token

Hello,

Background we've been using Openunison successfully in regards to k8s dashbard, grafana, argocd, etc. we also successfully used forward-auth0 (not to be confused with traefik-forward-auth) for authentication against Auth0 as idp we're now trying to have forward-auth0 utilize Openunison (via Application CR) as idp within the cluster.

Issue Authentication is successful. But the forward-auth0 access token request to openunison fails with OpenUnison server error.

We were wondering if you all had encountered similar before or had any thoughts or advice. (We couldn't determine the mechanism to increase Opeunison logging level.)

is there a stack trace after this? It would start with "Sendnig JSON Error"?

Also, what verion of the helm charts are you on?

hello,

we're using orchestra-login-portal-argocd via the ArgoCD Application Object - version: 2.3.38
(saw the recent versions to 2.3.41 but it breaks in other areas regarding groups and how we are using them I believe....We haven't had time to investigate and didn't want to introduce new variables into the mix. )

there's no stack trace, but here's fuller log context before and after:

nothing stands out. it's odd that there's no error in the logs. i've never used auth0 forward, so i'll try to get it up and running and see if i can reproduce

If you can email me directly, we can easily spin up a full temporary environment with everything in place and provide you access.

Thank you for the offer, but we reserve direct interaction for customers with support contracts, as we don't produce any closed source or "enterprise" editions that require licensing. If you're interested in a support contract, please reach out at https://www.tremolosecurity.com/contact/contact-us.

That said, I put together a debug build of 1.0.38 for you (the same version as is running per your helm chart) - docker.io/tremolosecurity/openunison-k8s-debug:1.0.38

This should have the build number 1.0.38-2023120501-DEBUG in the logs. I added an extra catch for errors, for some reason the error is being caught but not logged so hopefully this will find it. You can set the top level image option in your values.yaml and redeploy.

Completely understand, and thank you for the debug build. We'll try it out and let you know.
