OpenId Authentication

[SoniaNj]

Hi everyone,

I'm getting this error on configuring Keycloak authentication on LibreChat, I cannot get a registration or login via OpenID/Keycloak.
Can someone help with this please ?

LibreChat-API : 2025-09-12 19:18:58 error: ErrorController => error Unknown authentication strategy "openid"
LibreChat-API : 2025-09-12 19:18:59 error: ErrorController => error Unknown authentication strategy "openid"

When I access the callback URL in this format https://my_domain/oauth/openid/callback, it shows a blank page with this message :

An unknown error occurred.

I'm using this image :

ghcr.io/danny-avila/librechat-dev-api:latest

Here is my .env variables configuration :

OPENID_ISSUER=https://my_keycloak_domain/auth/realms/my_realm
OPENID_CLIENT_ID=LibreChat
OPENID_SESSION_SECRET=****
OPENID_SCOPE="openid profile email"
OPENID_CALLBACK_URL=/oauth/openid/callback
