"Could not find "README.md" in any of your source paths" when running rake dummy:app

When you are trying to run rake dummy:app from the rails-dummy gem and you get following message:

Could not find "README.md" in any of your source paths. Your current source paths are: 
/home/vagrant/.rvm/gems/ruby-2.4.0@cmor/gems/railties-5.2.0/lib/rails/generators/rails/app/templates

You may be using rails 5.2.0. Upgrading to 5.2.3 or later solves the problem.
