Rails generate method throwing error when using the gem with Rails 8

[vijayda1891]

Please help. After running bundle install and trying to use the command
rails g ratyrate User
getting the following error. I am using the latest version of rails and ruby
.local/share/mise/installs/ruby/3.4.2/lib/ruby/gems/3.4.0/gems/ratyrate-1.2.2.alpha/lib/generators/ratyrate/ratyrate_generator.rb:25:in 'RatyrateGenerator#create_model': undefined method 'exists?' for class File (NoMethodError)

raise "User model (#{model_file}) must exits." unless File.exists?(model_file)
                                                          ^^^^^^^^
