No link template 'canonical' found for the 'paragraph' entity type

Just got this too with Drupal 10 core, Paragraphs 8.x-1.15:

Drupal\Core\Entity\Exception\UndefinedLinkTemplateException: No link template 'canonical' found for the 'paragraph' entity type in Drupal\Core\Entity\EntityBase->toUrl() (line 196 of core/lib/Drupal/Core/Entity/EntityBase.php).

I just got this too when I updated from Drupal 9.5.2 to Drupal 9.5.4 core, Paragraphs 8.x-1.15:

The website encountered an unexpected error. Please try again later.

Drupal\Core\Entity\Exception\UndefinedLinkTemplateException: No link template 'canonical' found for the 'paragraph' entity type in Drupal\Core\Entity\EntityBase->toUrl() (line 196 of core/lib/Drupal/Core/Entity/EntityBase.php).

How to solve this issue? I still got this.

This patch works for us in D9.

See #20 for example. You fix this error enabling verbose errors with backtrace, see who is incorrectly calling toUrl() on an entity without checking if it has a canonical link template. It might be comments, there is an issue referenced above, or another contrib or custom module.

I'm seeing this on Paragraphs 1.15.

The site is a build with no custom code touching this area. The error is resolved with the rerolled patch at #17 is working for me. @akhilavnair, the only tweak I'd suggest is code standards on the comment.

Given there are many reports of this being resolved by fixing it in Paragraphs I'm unsure why this isn't just being resolved here.

It works. Using the patch at #17 with cwegans/composer-patches for now.

In my case I need a view of the all webform submissions with a links to source entity and it's a paragraph for some cases... so the system can't to get it and I see a whitescreen.

got this problem again in my drupal 9, after upgrade the core to 10, the problem stay exist

#17 was no longer applying for me.
Reroll #17

Rerolled patch at #35 applies and still works as expected.

Cheers @andysipple.
