Problem/Motivation

With live preview, we can add blocks to the layout builder, make updates, and see content changes in real-time. This is great.

We have discovered that this does not play nice with Field Blocks. When these blocks are added, such as the body field, it throws an Ajax error due to missing context on the entity.

Drupal\Component\Plugin\Exception\MissingValueContextException: Required contexts without a value: entity in Drupal\Core\Plugin\Context\ContextHandler->applyContextMapping() (line 155 of core/lib/Drupal/Core/Plugin/Context/ContextHandler.php).

Steps to reproduce

With Live Preview, add a field block via Layout Builder. I.e. a body field. Produces Ajax error.

Proposed resolution

Review and adjust for the missing context.

Remaining tasks

User interface changes

API changes

Data model changes
