Block Classes third party settings validation error when applying recipes via drush

[jjroelofs]

Problem

When applying DXPR CMS recipes via ddev drush recipe command, blocks with block_classes third party settings fail with validation errors like:

There were validation errors in block.block.dxpr_theme_views_block__case_studies_latest:
- third_party_settings.block_classes.block_class: 'block_class' is not a supported key.
- third_party_settings.block_classes: 'uuid' is a required key.
- third_party_settings.block_classes: 'langcode' is a required key.
- third_party_settings.block_classes: 'status' is a required key.
- third_party_settings.block_classes: 'dependencies' is a required key.
- third_party_settings.block_classes: 'id' is a required key.
- third_party_settings.block_classes: 'theme' is a required key.
- third_party_settings.block_classes: 'region' is a required key.
- third_party_settings.block_classes: 'weight' is a required key.
- third_party_settings.block_classes: 'provider' is a required key.
- third_party_settings.block_classes: 'plugin' is a required key.
- third_party_settings.block_classes: 'settings' is a required key.
- third_party_settings.block_classes: 'visibility' is a required key.

When selecting the case study recipe during site-installation in the UI (wizard) the block classes actually do get imported just fine despite warnings.

Affected Files

• recipes/dxpr_cms_case_study/config/block.block.dxpr_theme_views_block__case_studies_latest.yml
• recipes/dxpr_cms_multilingual/config/block.block.dxpr_theme_languageswitcher.yml

Expected vs Actual Behavior

• Expected: Block classes should apply correctly when installing recipes via ddev drush recipe
• Actual: Validation errors prevent recipe installation
• Note: Block classes work perfectly fine during initial site installation via the web interface

Root Cause

The block_classes module schema validation expects the third party settings to conform to a specific structure, but the current configuration only includes the block_class property. The validation seems to expect the entire block entity structure within the third_party_settings, which is incorrect.

Workaround

Currently removing block_classes third party settings from affected block configs:

third_party_settings: {}

Instead of:

third_party_settings:
  block_classes:
    block_class: 'container bg-primary-subtle py-4 px-3'

Steps to Reproduce

1. Install DXPR CMS ddev drush site-install dxpr_cms_installer dxpr_cms_installer_keys.dxpr_key='YOUR_DXPR_API_KEY' -y
2. Try to apply any recipe containing blocks with block_classes third party settings: ddev drush recipe ../recipes/dxpr_cms_case_study
3. Observe validation error
