Issue¶

After adding any block through Site studio "block" element, when previewing the component, you will get this error:

This block is broken or missing. You may be missing content or you might need to enable the original module.

Resolution¶

1. Check if the twig_tweak module is enabled.
2. If it is enabled and not in use, then this should be disabled, as the twig_tweak module is not compatible with Site Studio currently.

You can look for more information at: https://sitestudiodocs.acquia.com/8.0/user-guide/twig-tweak-module

Cause¶

The issue will occur only when adding the block to the pages through Site Studio block element, and not when added through block layout, because the twig_tweak incompatibility is with Site Studio and not Drupal. The drupal_block function defined in Site Studio's TwigExtension is overridden by twig_tweak's drupal_block function.
