Can't rending DT template

[Suliman via Digitalmars-d-learn]

I have this code:

module pages;
import vibe.d;
import database;
import vibe.web.web;
class MyPages
{
  @path("/page1")  void getPage()
    {
        render!("home.dt");
    }
}


The error: https://snag.gy/PtNeSs.jpg

Error: template instance 
vibe.web.web.render!"home.dt".render!("pages", 
"pages.MyPages.getPage").render.compileHTMLDietFile!("home.dt", 
req, DefaultFilters).exec!(StreamOutputRange!(OutputStream)) 
error instantiating

What I am doing wrong? Can I output html page instead of .dt?
