Issue with configuring OAuth2

[manojchandrashekar]

I have followed the documentation at: https://miniflux.app/docs/howto.html#oauth2 and I have setup the connection to my OAuth server.

Clicking on "Sign in with OpenID Connect" redirects to the OAuth server and on login, it redirects back to the login form on Miniflux.

These are the logs with DEBUG=on:

Do I have something wrong?
