ASP.NET Core 3 MVC endpoint routing and localization by route

I started messing with endpoint routing and url translation but i think i'm missing somthing.

My solution is here

I started from the example in this blog post

writing urls in address bar works as expected but I noticed that anchor tag don't generate url at all.

Layout sample

     @{ 
         Dictionary<string, string> routePol = new Dictionary<string, string>();
         routePol.Add("language", "pl");
         routePol.Add("controller", "Home");
         routePol.Add("action", "Index");
    }
    <a asp-all-route-data="routePol">Poland</a>

should generate 

<a href="test/pl/Home/Index">Poland<a>

result 

<a href >Poland<a>

Main endpoint

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapDynamicControllerRoute<TranslationTransformer>(
                    "{language=pl}/{controller=orders}/{action=list}");
            });

I don't understand what is wrong. I read around that with endpoint routing, anchor tag does not generate urls when the provided values generate a not existing route, but the route above should be valid.

If it's possible, is there a way to debug how route is validated or log errors?

EDIT: problem now solved, thanks to Rena. I updated my solution with fixes and I added a useful component for culture change using route value, hope that will be useful to everyone that will stumble in same problems as me.

The blog show us how to translate the url when you send request.But in your case,you just want to render url,it should add route template to match it.

Here is a smiple workaround like below:

1.View:

@{
Dictionary<string, string> routePol = new Dictionary<string, string>();
routePol.Add("language", "pl");
routePol.Add("controller", "zamowienia");
routePol.Add("action", "lista");    
}
@*controler name and action name should be the key name in TranslationDatabase 
not the value name.*@
<a asp-all-route-data="routePol">Poland</a>

2.Startup.cs:

app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{language=pl}/{controller=orders}/{action=list}");
            endpoints.MapDynamicControllerRoute<TranslationTransformer>(
                "{language=pl}/{controller=orders}/{action=list}");

        });

It would generate the url:/pl/zamowienia/lista and when you click the link,it would get into orders/list action
