When adding and viewing a new View for listing entity_subqueue entities, the following fatal error occurs:

Drupal\Core\Entity\Exception\UndefinedLinkTemplateException: No link template 'canonical' found for the 'entity_subqueue' entity type in Drupal\Core\Entity\Entity->toUrl() (line 225 of /var/www/drupal8/php/web/core/lib/Drupal/Core/Entity/Entity.php).

Adding the canonical link to the entity links definition fixes the issue.

 *   links = {
 *     "canonical" = "/admin/structure/entityqueue/{entity_queue}/{entity_subqueue}",
 *     "edit-form" = "/admin/structure/entityqueue/{entity_queue}/{entity_subqueue}",
 *     "delete-form" = "/admin/structure/entityqueue/{entity_queue}/{entity_subqueue}/delete",
 *     "collection" = "/admin/structure/entityqueue/{entity_queue}/list",
 *   },

Just noting, the test failure appears unrelated to the patch instead:

queue name & id mismatch: tests/modules/entityqueue_test/config/install/entityqueue.entity_queue.test.yml > id: test_queue

I imagine the file should be named entityqueue.entity_queue.test_queue.yml
or the id should be just test

Ah, wrote too soon on this one. It fixes the error, but turns the edit form into a read-only type display.
Looks like we'll need a separate route for the canonical entity subqueue url instead of sharing the edit-form.

When adding and viewing a new View for listing entity_subqueue entities, the following fatal error occurs

I could not reproduce this error. I made a simple queue, and a 'multiple subqueue' entity queue. I added some content to each queue.

Next, I went to /admin/structure/views/add and selected Entity subqueue in the "View Settings" section, and created a page.

I clicked save, and went to the page, and had no issues.

I'm on the 8.x-1.x branch for entityqueue (Currently on the commit caeff5d96411a9ceceddf3d12343844eb228838f on Jul 11, 2018)
I'm running Drupal 8.5.5

Update:

I switched to Drupal 8.6-dev, and I still cannot reproduce this bug.
@davidwhthomas, can you still reproduce this?

Duplicate of #2862628: No link template 'canonical' found for the 'entity_subqueue' entity type. There was a core bug which fixed a similar thing: #2479377: content_translation_page_attachments() should check for a canonical link before generating a URL to it so I assume somewhere in the codebase of your project you have a similar situation with a module (or even core) which doesn't check if a canonical link template actually exists before doing its work.

Thanks for the update!

I'm running v8.5.4

I'll double check it again with the custom view, perhaps ok for now.
