Fix fatal error on Varbase Workflow settings form after Drupal 11.2.0

Created on 7 August 2025, 9 days ago

After updating to Drupal 11.2.0, a fatal error occurs on the Varbase Workflow settings page:

/admin/config/varbase/varbase-workflow

This is caused by a backward-incompatible change in the constructor of Drupal\Core\Form\ConfigFormBase, which now requires a RequestStack service as the second parameter. The current implementation in VarbaseWorkflowSettingsForm only injects the ConfigFactoryInterface.

Error:

ArgumentCountError: Too few arguments to function Drupal\Core\Form\ConfigFormBase::__construct(), 
1 passed in ... and exactly 2 expected in ConfigFormBase.php on line 44.

Steps to reproduce

Given I am logged in with the “webmaster” user
When I navigate to "/admin/config/varbase/varbase-workflow"
Then I hit a fatal error

The website encountered an unexpected error. Try again later.

ArgumentCountError: Too few arguments to function Drupal\Core\Form\ConfigFormBase::__construct(), 1 passed in /app/docroot/modules/contrib/varbase_workflow/src/Form/VarbaseWorkflowSettingsForm.php on line 64 and exactly 2 expected in Drupal\Core\Form\ConfigFormBase->__construct() (line 44 of core/lib/Drupal/Core/Form/ConfigFormBase.php).
