	log.SetFormatter(gcplog.NewFormatter())

	e := echo.New()

	e.Use(middleware.RequestLoggerWithConfig(middleware.RequestLoggerConfig{
		LogError:        true,
		LogStatus:       true,
		LogLatency:      true,
		LogResponseSize: true,
		LogValuesFunc: func(c echo.Context, v middleware.RequestLoggerValues) error {
			l := log.WithField("httpRequest", &gcplog.HTTPRequest{
				Request:      c.Request(),
				Status:       v.Status,
				Latency:      v.Latency,
				ResponseSize: v.ResponseSize,
			})

			if v.Error != nil {
				l.Error(v.Error)
			} else {
				l.Info()
