When used with other contrib modules like responsive_preview → , clicking Edit or Delete on a local font triggers WSOD.
Symfony\Component\Routing\Exception\RouteNotFoundException: Route "entity.local_font_config_entity.canonical" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 206 of core/lib/Drupal/Core/Routing/RouteProvider.php).
The local_font entity canonical link is defined but not a corresponding route. When another module calls something like $entity->toUrl() it fails.
Use Drupal 10.2.4 & fontyourface 4.0.0
Enable local_fonts module
Create and upload a local font
Click Edit or Delete
Remove the canonical entity link.
Active
4.0
Local Fonts (provider)
Kindly push this to the main release version 4.0. Still getting the WSOD on all my themes in Drupal 10
