"missing ID token: <nil>" on successful login #78

Hi, I'm trying to use this wonderful tool (thanks!) in my company development server.

I got to the point where I can login with Microsoft OIDC, but after a correct login I get a "Bad Gateway" page. The logs shows "missing ID token ".

This is my docker compose (some of the envvars are there after a trial and error phase, not sure if I need them all):

version: "3.3"

services:
  traefik:
    image: "traefik:latest"
    restart: always
    ports:

Here's the full log (tenant, client id and domains are ok, I've obscured them):

I don't understand if it's a configuration problem, a traefik-forward-auth bug or a microsoft OIDC limitation. What am I missing here?

Thanks in advance for any help!

After examining the OpenID Connect scopes allowed by Microsoft, I tried to set the SCOPE envvar to openid,email,profile (groups is not supported), but now I get the following (reformatted for readability):

I solved going back to thomseddon/traefik-forward-auth that has the right scopes by default.

I suppose that the SCOPE doesn't manage the user input as it should (I see that it is defined as a simple string, not as CommaSeparatedList).
