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

Updating the patch to cover this use cases:

• There isn't a node in the root parent.
• We don't get a node from parents.

#5 worked fine, Thank you

#5 reviewed and tested on my system. Works fine. Marking it as RTBC

Extend #5 with check for node->id because, toUrl method is throwing error if node is not created and doesn't have id. Case scenario when user want to preview node.

I saw this same error adding an image to a accordion section. Im just adding <img/> element to text body as a workaround.

same error i'm getting in drupal 9.3 version.
i am using paragraph module , i have created an view of paragraph and using fields image and text when i try to link image with content then the module has throw an exception that is ....Below -

Drupal\Core\Entity\Exception\UndefinedLinkTemplateException: No link template 'canonical' found for the 'paragraph' entity type in Drupal\Core\Entity\EntityBase->toUrl()

issue described by me above is related to paragraph module. if any patch implemented for this issue please tell about that.

Thank You.

This is a newbie question, but where do we insert the #5 patch?

@JennBina you'll need a composer based project.
See: https://devdocs.magento.com/guides/v2.4/comp-mgr/patching/composer.html

Replace the code of addtoany.module file below code :

use Drupal\node\NodeInterface;
 
 /**
  * Implements hook_theme().
@@ -192,8 +193,12 @@ function addtoany_page_attachments(&$page) {
  *   The array with url, title, additional_html that will be send to Twig.
  */
 function addtoany_create_entity_data($node, $config = NULL) {
  while ($node instanceof EntityInterface && $node->getEntityTypeId() == 'paragraph') {
    $node = $node->getParentEntity();
  }

  $url = $node instanceof NodeInterface ? $node->toUrl('canonical', ['absolute' => TRUE])->toString() : NULL;
 $title = $node instanceof NodeInterface ? $node->label() : NULL;
   return addtoany_create_data($url, $title, $config);
 }

Theres something critically wrong with the patch. How is it the case that this statement is ever true?

while ($node instanceof EntityInterface && $node->getEntityTypeId() == 'paragraph') {

$node should only ever be a NodeInterface.

Unless addtoany_create_entity_data is truely supposed to be able to handle any entity type, then the entire function signature and documentation needs to change to take any arbitrary entity type.

So function addtoany_create_entity_data($node, $config = NULL) { changes to function addtoany_create_entity_data(ContentEntityInterface $entity, $config = NULL) { After which the entire function should be guarded/early-return with a link template check:

if (!$entity instanceof ContentEntityInterface || !$entity->hasLinkTemplate('canonical') {
  return;
}

I've updated the patch in #15. Mostly by adding some type casting to the $entity object that gets passed in and adding some commenting around the changes. That should simplify some of the conditional logic happening in the function.

The paragraphs can be nested inside another paragraphs. Here is patch version that handle this case as well.
