Ok - My next step would be to enable Debugging to Developer level (if you haven't already) and then create the error with the Network tab open in your browser. A lot of items are returned and you need to search for the one with the error. It'll almost certainly be in the last few and have a path with service.php in it somewhere. I think you should find something that looks like error messages in the response.

Open your browser's javascript console (F12 then 'console' tab). Recreate the error. Any red error messages in the console?
Are you talking about this optional plugin - https://moodle.org/plugins/auth_oidc ?
I don't know anything about it, but 'oidc' would be logical - the name of the plugin folder under auth/.
Good that you got it working - but I can't see any situation where you should have had to modify the config table directly. But none of those settings are anything "interesting".
