Problem/Motivation
Draft mode returns wrong revision of includes. I get default revision of second level paragraph instead of latest revision.
Technical problem:
When trying to access the working revision entity data with resourceVersion=rel:working-copy and using includes, the current revision of the referenced entities is being returned by the method "resolveIncludeTree" in IncludeResolver class. This method should return the data as per the revision being passed in the API query or the working revision.
Steps to reproduce
Install Content moderation;
Add support version negotiation for any entity type: "https://git.drupalcode.org/project/drupal/-/merge_requests/1365.patch"
Create paragraph type A;
Create paragraph type B;
Add paragraph reference field to paragraph A;
Create node with paragraph A (+ paragraph B inside A)
Publish node;
Create draft with changed B;
Check node json data with resourceVersion=rel:working-copy. Returned wrong revision of includes.
Proposed resolution
web/core/modules/jsonapi/src/IncludeResolver.php
loads included entity by id
$targeted_entities = $entity_storage->loadMultiple(array_unique($ids));
I suggest to load entities by revision id:
$targeted_entities = $entity_storage->loadMultipleRevisions(array_unique($revision_ids));
