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: rest.rb
    path of file: ./repos/puppet/lib/puppet/indirector/file_content
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require_relative '../../../puppet/file_serving/content'
require_relative '../../../puppet/indirector/file_content'
require_relative '../../../puppet/indirector/rest'

class Puppet::Indirector::FileContent::Rest < Puppet::Indirector::REST
  desc "Retrieve file contents via a REST HTTP interface."

  def find(request)
    content = StringIO.new
    conte
    
  def find(request)
    content = StringIO.new
    content.binmode

    url = URI.parse(Puppet::Util.uri_encode(request.uri))
    session = Puppet.lookup(:http_session)
    api = session.route_to(:fileserver, url: url)

    api.get_file_content(
      path: Puppet::Util.uri_unescape(url.path),
      environment: request.environment.to_s
    ) do |data|
      content << data
    end

    Puppet::FileServing::Content.from_binary(content.string)
  rescue Puppet::HTTP::ResponseError => e
    if e.response.code == 404
      return nil unless request.options[:fail_on_404]

      _, body = parse_response(e.response)
      msg = _("Find %{uri} resulted in 404 with the message: %{body}") % { uri: elide(e.response.url.path, 100), body: body }
      raise Puppet::Error, msg
    else
      raise convert_to_http_error(e.response)
    end
