Router don't catch panic

[ad3n]

func Index(ctx *fasthttp.RequestCtx) {
	ctx.WriteString("Welcome!")
}

func Hello(ctx *fasthttp.RequestCtx) {
	fmt.Fprintf(ctx, "Hello, %s!\n", ctx.UserValue("name"))
}

func main() {
	r := router.New()
	r.GET("/", Index)
	r.GET("/{name1}/{name3}", Hello)
        r.GET("/{name}/{name3}", Hello)

	log.Fatal(fasthttp.ListenAndServe(":8080", r.Handler))
}

Expected catch panic
