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: graphql_controller.rb
    path of file: ./repos/gitlabhq/app/controllers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class GraphqlController < ApplicationController
  extend ::Gitlab::Utils::Override

  # Unauthenticated users have access 
    
  def append_info_to_payload(payload)
    super

    # Merging to :metadata will ensure these are logged as top level keys
    payload[:metadata] ||= {}
    payload[:metadata][:graphql] = logs

    payload[:exception_object] = @exception_object if @exception_object
  end
