Trying to obtain RequestId within Request return empty

[terzano]

I initialized the middleware.

e.Use(middleware.RequestID())

I can see the X-Request-Id header entry in the response.
X-Request-Id: jx7ZobWWoEJE9yFGJsNyOslFUVihYCQL

However, I am unable to obtain the RequestId within the request/response cycle.
This is returning empty in my case. Any ideas? id variable.

func foo(c echo.Context) error {    
    id := c.Response().Header().Get(echo.HeaderXRequestID)
    ...
}

I am able see get id with this example:

func main() {
	e := echo.New()
	e.Use(middleware.RequestID())

	e.GET("/", func(c echo.Context) error {
		id := c.Response().Header().Get(echo.HeaderXRequestID)
		return c.String(http.StatusOK, id)
	})

	if err := e.Start(":8080"); err != http.ErrServerClosed {
		e.Logger.Fatal(err)
	}
}

that middleware config has also RequestIDHandler that you can use to set id value to context store

func main() {
	e := echo.New()
	e.Use(middleware.RequestIDWithConfig(middleware.RequestIDConfig{
		RequestIDHandler: func(c echo.Context, s string) {
			c.Set("MY_REQUEST_ID", s)
		},
	}))

	e.GET("/", func(c echo.Context) error {
		id, _ := c.Get("MY_REQUEST_ID").(string)
		return c.String(http.StatusOK, id)
	})

	if err := e.Start(":8080"); err != http.ErrServerClosed {
		e.Logger.Fatal(err)
	}
}

@aldas Thank you very much for the advice on the custom handler, it worked perfectly.
Getting the RequestId from the header works for me as well on a Hello Word type app like you described but for some reason on my larger application is returning empty. I will have to debug more in depth to see if another middleware is causing the problem.
In the meantime, the RequestIDHandler is working perfectly.

Again Thank you very much for your help.
