Ruby zip a folder - rubyzip

ruby_zip_demo.rb

require 'zip'

input_directory = '' # directory to be zipped
zipfile_name = '' # zip-file name

# zip a folder with only files (NO SUB FOLDERS)
Zip::File.open(zipfile_name, Zip::File::CREATE) do |zipfile|
  Dir[File.join(input_directory, '*')].each do |file|
    zipfile.add(file.sub(input_directory, ''), file)
  end
end

# zip a folder with files and subfolders
Zip::File.open(zipfile_name, Zip::File::CREATE) do |zipfile|
   Dir["#{input_directory}/**/**"].each do |file|
     zipfile.add(file.sub(input_directory + '/', ''), file)
   end
end

Found the issue, thanks:)
