"an error ocurred" when receiving the callback from google

[mgs96]

Hello, I'm trying to implement omniauth with google, I was able to redirect to google, select account and then redirect to the callback route, but I'm getting an error ocurred error when rendering omniauthsuccess, the users are being created, I can see them in the rails console, I have already looked some tutorials like this one but no success

the versions of the gems are the following:

• devise (4.3.0)
• devise_token_auth (0.1.42)
• oauth2 (1.4.0)
• omniauth (1.8.1)
• oauth2 (1.4.0)
• omniauth (1.8.1)
• omniauth-google-oauth2 (0.5.3)
• omniauth-oauth2 (1.5.0)
• rails (5.1.4)

The project was created using the --api flag, I have already configured the devise initializer.

Devise.setup do |config|
    config.navigational_formats = [ :json ]
    config.mailer_sender = "[email protected]"
    config.omniauth :google_oauth2, ENV["GOOGLE_KEY"], ENV["GOOGLE_SECRET"], {}
end

the routes are the following:

Rails.application.routes.draw do
  mount_devise_token_auth_for 'User', at: 'auth', controllers: { omniauth_callbacks: 'users/omniauth_callbacks' }, defaults: { format: :json }

  get 'login', to: redirect('/auth/google_oauth2'), as: 'login'
  get 'logout', to: 'sessions#destroy', as: 'logout'
  get 'auth/failure', to: redirect('/')

  # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
  namespace :api do
    namespace :v1 do
      resources :products
    end
  end
end

currently I'm not using any front end, just testing in my browser.

Thanks in advance.. and If I'm able to pull this off, I will gladly contribute with a tutorial, or a README, or something, thanks again

Try to make like this - it works for me

provider :google_oauth2, ENV["GOOGLE_KEY"], ENV["GOOGLE_SECRET"],
{
    display: 'popup',
    prompt: 'select_account consent',
    access_type: 'offline',
    scope: 'userinfo.email',
    redirect_uri: 'http://HOST_APP/omniauth/google_oauth2/callback'
}
