Undefined local variable or method with developer strategy?

[nolyoi]

Configuration

• Provider Gem: omniauth
• Ruby Version: 2.7.1
• Framework: Rails 6
• Platform: Ubuntu 20.04

Expected Behavior

I am expecting the user to be created using the developer strategy on my local env. According to the docs auth['info']['name'] and auth['uid'] are the correct way to retreive this hash, no?

Actual Behavior

undefined local variable or method auth' for #SessionsController:0x000055a2ebdbce80`

Steps to Reproduce

Here is how my controller is currently configured.

  def omni
    @user = User.find_or_create_by(uid: auth['uid']) do |u|
      u.name = auth['info']['name']
      u.uid = auth['uid']
    end

    pp request.env['omniauth.auth']
    session[:user_id] = @user.id
    
    redirect_to root_path
  end

I experienced something like this;
Have you included
:omniauthable, omniauth_providers: %i[github facebook](change accordingly with your provider name) in your model?
in any case i suggest to follow the wiki about omniauth on devise https://github.com/heartcombo/devise/wiki/OmniAuth:-Overview
