Missing route: entity.encryption_profile.canonical

5 years later I was able to reproduce this one. In my case is in combination with the Next.js → Drupal module.

Instructions to reproduce:

1. Create an encryption profile
2. Install Next.js module and its dependencies (no worries, no need to configure).
3. Delete your encryption profile through the UI.
4. WSOD !

The issue is due to EncryptProfile config entity declares a "canonical" path in its "links" section, but doesn't implement it:

https://git.drupalcode.org/project/encrypt/-/blob/8.x-3.x/src/Entity/Enc...

Drupal example on configuration entities → does not include a "canonical" path. Also when creating such entity with drush gen entity:configuration, the resulting entity does not contain such path, and the module does not use it.

Hence, my suggestion would be to remove that line, which actually fixes the issue.

Please check the attached patch. It does not contain a test. I could try writing it, but not sure its actually wanted. Not breaking the other tests might be enough in this case.

BTW the code in Next.js triggering the error is something like this, in a generic hook_entity_predelete, which seems quite right:

if ($entity->hasLinkTemplate('canonical')) {
  $url = $entity->toUrl();
}

Patch in #5 solved it for me. I wouldn't think there needs to be a canonical path for encryption profiles anyways.

I've been just ignoring the error for a while and finally decided to see if there was anyone with the same issue. Glad I waited until today.

I ran into the same error, just trying to edit my encryption profile.

The patch in #5 fixes it for me.

Might we get a release?

Many thanks!

Committed, thanks!
