Gutenberg editor fails to load with Group module - JavaScript destructuring error

Open on Drupal.org →
Created on 10 July 2025, about 2 months ago

When using the Gutenberg with the Group → module, attempting to add or edit nodes through Group module routes (e.g., adding content to a group) results in a JavaScript error that prevents the Gutenberg editor from loading:

gutenberg.js:147 Uncaught (in promise) TypeError: Cannot destructure property 'contentType' of 'format.editorSettings' as it is null.
    at Object.attach (gutenberg.js:147:15)

Steps to Reproduce

  • Install and enable both Gutenberg and Group modules
  • Create a group
  • Configure a content type to use Gutenberg editor
  • Navigate to add content to the group (e.g., /group/1/content/add/group_node:article)
  • Observe the JavaScript error in browser console and Gutenberg editor fails to load

Root Cause

The GutenbergContentTypeManager::getGutenbergNodeTypeFromRoute() method correctly invokes the hook_gutenberg_node_type_route hook for custom routes, but no implementation exists for Group module routes (entity.group_relationship.create_form and entity.group_relationship.edit_form).

Proposed Solution

Implement the hook_gutenberg_node_type_route() hook to handle Group module routes, as documented in gutenberg.api.php.oup module compatibility.
