Routing debug issues

Affected version(s)

Contao 4.9

Description

I tried to debug some routes with vendor/bin/contao-console route:match but get following errors:

vendor/bin/contao-console route:match /preview.php/_wdt/205c80

In RouteProvider.php line 115:
                                                                                                                                                   
  Return value of Contao\CoreBundle\Routing\RouteProvider::getRouteByName() must be an instance of Symfony\Component\Routing\Route, null returned                                        

I locally fixed it with following condition, I'm able to select a route:

if (!isset($routes[$name])) {
    throw new RouteNotFoundException('Route name does not match a page ID');
}

 [OK] Route "tl_page.893.error_404" matches                                                                             
                                                                                                                        
 Select one of the matching routes:
  [0] tl_page.893.error_404.locale
  [1] tl_page.893.error_404

If I select any I get another error now:

  The route "tl_page.893.error_404" does not exist.
