Entity Reference display formatter currently doesn't check if the entity has canonical path or not, by default, it display the entity with a link.

This will encounter a WSOD when the entity doesn't have a canonical path.

Here is one test example: https://www.drupal.org/node/2826470#comment-11801660

As far as I can see, a check for this was added in #2704743: Remove special case on EntityFormatter for new entities which hopefully solved this problem.

Code now in \Drupal\Core\Field\Plugin\Field\FieldFormatter\EntityReferenceEntityFormatter::viewElements:

      if (!empty($items[$delta]->_attributes) && !$entity->isNew() && $entity->hasLinkTemplate('canonical')) {
        $items[$delta]->_attributes += ['resource' => $entity->toUrl()->toString()];
      }

That $entity->hasLinkTemplate('canonical') check was missing before this and that might have caused this bug.

If this is still an issue for you, could you provide some steps to reproduce this issue?
