You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: s3_bucket_config.rb
    path of file: ./repos/jets/engines/internal/app/shared/functions/jets
    
    the code of the file until where you have to start completion: require 'bundler/setup'
require 'active_support/core_ext/hash'
require 'cfn_response'

def lambda_handler(event:, context:)
  cfn = CfnResponse.new(event, context)
  cfn.response do
    case event['Reques
    
def lambda_handler(event:, context:)
  cfn = CfnResponse.new(event, context)
  cfn.response do
    case event['RequestType']
    when "Create", "Update"
      properties = event["ResourceProperties"].dup
      # After deleting ServiceToken, the rest of the values are the bucket configuration properties.
      properties.delete("ServiceToken")
      configurator = BucketConfigurator.new
      configurator.put(properties)
    end
  end
