      class SerializeResponse
        def self.call(env)
          headers = { 'Content-Type' => 'text/plain' }.merge(env.response_headers || {})
          if env.response
            [200, headers, [env.response]]
          else
            [404, headers, ['Not Found']]
          end
        end
      end

      class CorsHeaders
        def initialize(app)
          @app = app
        end

        def call(env)
          status, headers, body = @app.call(env)
          headers.merge!(
