Cannot install because trait LayoutEntityHelperTrait missing

Created on 15 August 2025, 2 months ago

Problem/Motivation

When I try to install Patternkit on a standard profile Drupal 11.2 site, I get this error:

PHP Fatal error:  Trait "Drupal\layout_builder\LayoutEntityHelperTrait" not found in /var/www/web/modules/contrib/patternkit/src/LayoutHelper.php on line 26

Steps to reproduce

- Install Drupal 11.2 with the standard profile
- Try to enable Patternkit module
- Observe the error noted above?

Proposed resolution

Make Patternkit dependent on Layout Builder? Or somehow only load LB's traits conditionally, e.g., if LB is itself enabled?

@krisahil, we had been looking at marking the Layotu Builder module as required already, so we'll move forward with your suggestion of doing so. I've uploaded an MR making this change.
