rails admin undefined method `new' for nil:NilClass error

I'm getting an error message when I try to go inside the admin dashboard by the rails_admin gem.

Error

undefined method `new' for nil:NilClass

This is the whole code 

          klass.setup if klass.respond_to? :setup
          @authorize = proc do
            @authorization_adapter = klass.new(*([self] + args).compact)
          end
        elsif block
          @authorize = block

It is pointing to this spot

            @authorization_adapter = klass.new(*([self] + args).compact)

I don't know why this happening because I did not touch anything from the rails admin

To anyone who is scratching their head over this issue and stumbled upon this thread, on /config/initializers/rails_admin.rb try replacing

config.authorize_with :cancan

with

config.authorize_with :cancancan
