Canonical Entity Link problems

Example:

The Module Responsive Preview checks if an entity has a canonical link and will then use that to build it's own URL for checking the page. This module's entity annotation defines that it should have a canonical url but that doesn't actually exist.

The website encountered an unexpected error. Try again later.

Symfony\Component\Routing\Exception\RouteNotFoundException: Route "entity.block_visibility_group.canonical" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 206 of core/lib/Drupal/Core/Routing/RouteProvider.php).

Drupal\Core\Routing\UrlGenerator->getRoute('entity.block_visibility_group.canonical') (Line: 276)
Drupal\Core\Routing\UrlGenerator->generateFromRoute('entity.block_visibility_group.canonical', Array, Array, 1) (Line: 108)
Drupal\Core\Render\MetadataBubblingUrlGenerator->generateFromRoute('entity.block_visibility_group.canonical', Array, Array, ) (Line: 765)
Drupal\Core\Url->toString() (Line: 109)
Drupal\responsive_preview\ResponsivePreview->getPreviewUrl() (Line: 327)
Drupal\responsive_preview\ResponsivePreview->previewToolbar() (Line: 33)

Thanks for putting that together. And yeah, I don't think this custom entity type should have a canonical URL either.

Patch fixed our issue.

Thank you @emerham
The patch is working for me after apply below code and cleared cache.

            "drupal/block_visibility_groups": {
                "Canonical Entity Link problems": "https://git.drupalcode.org/project/block_visibility_groups/-/merge_requests/9.patch"
            }

@ Maintainers - is possible to me this MR so we don't need to apply patch.

Committed. Thank you all!
