Fatal error: Declaration of Drupal\dsl\Form\DslDomainConfigSettingsForm when updating domain_site_settings

Problem/Motivation

I'm getting this error after updating domain_site_settings:

Fatal error: Declaration of Drupal\dsl\Form\DslDomainConfigSettingsForm::buildForm(array $form, Drupal\Core\Form\FormStateInterface $form_state) must be compatible with Drupal\domain_site_settings\Form\DomainConfigSettingsForm::buildForm(array $form, Drupal\Core\Form\FormStateInterface $form_state, ?Drupal\domain\DomainInterface $domain = NULL) in /var/www/html/docroot/modules/contrib/dsl/src/Form/DslDomainConfigSettingsForm.php on line 17

Steps to reproduce

Update domain_site_settings, then clear the cache, you should be getting the error.

Proposed resolution

Fix this in the module.

Remaining tasks

User interface changes

API changes

Data model changes
