Since you have a class called Common::RestClient and are using a ruby gem which defines a class RestClient, when you're within your Common module, you'll need to reference the gems RestClient with a :: prefix, otherwise, it assumes you're talking about Common::RestClient

module Common
  module RestClient

  def call_rest_service_get(url)
    begin
      response = ::RestClient.get(url, {accept: :json})
    rescue ::RestClient::Exception => err
      return err.response
    else
      return response
    end
  end
end
