I'd like to use attribute routing and also named routes. When I remove the default route in Startup.cs and use the [Route] and [HttpGet] attributes in my controller, the 404 page no longer gets rendered by the SPA.

[Route("")]
public class HomeController : Controller
{
    [HttpGet("", Name = HomeControllerRouteName.GetIndex)]
    public IActionResult Index() => this.View();

    [HttpGet("error", Name = HomeControllerRouteName.GetError)]
    public IActionResult Error()
    {
        this.ViewData["RequestId"] = Activity.Current?.Id ?? this.HttpContext.TraceIdentifier;
        return this.View();
    }
}

.UseMvc(routes =>
{
    routes.MapSpaFallbackRoute(
        name: "spa-fallback",
        defaults: new { controller = "Home", action = "Index" });
})

Why does the MapSpaFallbackRoute not work with attribute and named routes?
How can I specify a route name instead of a controller and action name with MapSpaFallbackRoute?
