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: engine.rb
    path of file: ./repos/eyeloupe/lib/eyeloupe
    
    the code of the file until where you have to start completion: require 'importmap-rails'

module Eyeloupe
  class Engine < ::Rails::Engine
    isolate_namespace Eyeloupe

    initializer "eyeloupe.assets" 
    
        def request(req, body = nil, &block)
          res, ex = nil
          exception_processor = Eyeloupe::Processors::Exception.instance
          out_request_processor = Eyeloupe::Processors::OutRequest.instance

          if Eyeloupe.configuration.capture
            begin
              out_request_processor.init(req, body)
              res = original_request(req, body, &block)
            rescue => e
              ex = exception_processor.process(nil, e)
            ensure
              out_request_processor.process(res, ex)
            end
