I noticed the version 1.5.1 of this gem added this #24 change. This change added request_phase method here. However what this is doing for me is that it's overwriting scope that I have set when configuring the provider like this:

    provider(:keycloak_openid,
             "client_id",
             "client_secret",
             name: "keycloak",
             scope: "openid", # <-- this line here!!!
             client_options: {
                 # Base url as empty, defaults to "/auth/..." base url.
                 base_url: "", site: "keycloak_url_here", realm: "test_realm"
             })

What is basically happening is the request_phase method is overwriting my scope with nil instead of "openid". This in turn causes Keycloak not to return ID token for me anymore.

I could provide a fix for this but not sure if I'm setting the scope correctly. Or could this be fixed in the gem to conditionally set value from request.params if it's nil? Maybe something along these lines:

def request_phase
  options.authorize_options.each do |key|
    options[key] = request.params[key.to_s] if options[key].nil?
  end
  super
end
