i also got the same error, is there any update?

I feel like this is related to #1061, since the template you're using uses Rails 7

@alec-c4 have you found a fix? im having the same issue

Since omniauth set omniauth.auth by detect path in rack middleware, you can find out why omniauth.auth is empty by this :

bundle open omniauth

# edit  lib/omniauth/strategy

289     def on_callback_path?
290       puts "oncall path?: #{on_path?(callback_path)} #{callback_path}, ----- current_path: #{current_path}" # if current_path =~ / filter path/
291       on_path?(callback_path)
292     end

devise_for :user, controllers: {   omniauth_callbacks: 'user/omniauth_callbacks' }
devise_scope :user do
    get '/auth/google_oauth2/callback' => 'user/omniauth_callbacks#google_oauth2', :as => :google_oauth2_callbacks
end

When I Changed Route ,I Got this issue
/user/auth/google_oauth2/callback => /auth/google_oauth2/callback
