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: configuration.rb
    path of file: ./repos/vets-api/lib/bb
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'common/client/configuration/rest'
require 'common/client/middleware/request/camelcase'
require 'common/client/middleware/response/json_parser'
require 'common/cli
    
    def connection
      Faraday.new(base_path, headers: base_request_headers, request: request_options) do |conn|
        conn.use :breakers
        conn.request :camelcase
        conn.request :json

        # Uncomment this if you want curl command equivalent or response output to log
        # conn.request(:curl, ::Logger.new(STDOUT), :warn) unless Rails.env.production?
        # conn.response(:logger, ::Logger.new(STDOUT), bodies: true) unless Rails.env.production?

        conn.response :betamocks if Settings.mhv.bb.mock
        conn.response :bb_parser
        conn.response :snakecase
        conn.response :raise_error, error_prefix: service_name
        conn.response :mhv_errors
        conn.response :mhv_xml_html_errors
        conn.response :json_parser

        conn.adapter Faraday.default_adapter
      end
    end
