Error: Call to a member function getValue() on null in ebt_basic_button_preprocess_block() (line 36 of ebt_basic_button.module

Hi thomas kaisuka, thank you for your report, I added additional validation for field_ebt_settings:
https://www.drupal.org/project/ebt_basic_button/releases/1.4.11 →
https://drupalbook.org/ebt/demo/basic-button

The new change is now bringing this and a WSOD ;

Error: Call to a member function hasField() on null in ebt_basic_button_preprocess_block() (line 41

I see.. there are two places with block_content:
$variables['elements']['content']['#block_content']
$variables['content']['#block_content']

I added validation for both of them:
https://www.drupal.org/project/ebt_basic_button/releases/1.4.12 →

But then preprocess will not be working. Did you face this problem on Drupal 11 after upgrade from Drupal 10? I'm still waiting to upgrade from Drupal 10 to Drupal 11 cause of CKEditor 5 plugins, but eventually I will upgrade my site drupalbook.org and test all EBT/EPT modules with Drupal 11 too.
