error: ErrorController => error Unknown authentication strategy "openid" when using OIDC

Deployed LibreChat latest version on to Kubernetes. Set OIDC in the .env file as per below (Keycloak as authorization server also deployed to Kubernetes) and created the secret librechat-credentials-env from the .env file

Open LibreChat https://librechat.poc, login page comes up, Click on "Continue with OpenID", browser gets redirected to "https://librechat.poc/oauth/openid"

in the server log, i can see this

I have seen other tickets in the past reporting similar issues using OIDC in LibreChat which seems to have been fixed. In my test scenario above, i can't work out what it's causing it.
