Template is not rendered in AfterMiddleware

[euclio]

I'm trying to implement a custom 404 handler that renders a handlebars template. I have the following code:

struct ErrorHandler;

impl AfterMiddleware for ErrorHandler {
    fn catch(&self, _: &mut Request, err: IronError) -> IronResult<Response> {
        if let Some(_) = err.error.downcast::<NoRoute>() {
           Ok(Response::with((status::NotFound, Template::new("not_found", ()))));
        } else {
            Err(err)
        }
    }
}

I have made sure that the template is registered (my other templates work correctly), and that the middleware is linked. However, there is no body in the response. "Not found" is returned in the body if I replace the Template::new with "Not found".

hi @euclio , could you please confirm the ErrorHandler in the chain was before the HandlebarsEngine?
