The domain is not being configured on the homepage created when you create the subdomain

The patch for this.

Hi @developer-rocha, thanks for the report of this issue. It is indeed a bad decision and coding from me that i hardcoded it to 'nl'.

But you should get the language from the configured content type rather than the sites default language.
Something in the line of:

$entityTypeManager = \Drupal::service('entity_type.manager');
$content_type = $entityTypeManager->getStorage('node_type')->load($type);
$default_language = $content_type->get('langcode');

Get the language from the content type. Needs a little testing tho to make sure it works with all settings on the content type.
So when no language is passed, fall back to the sites default language.

Hi @tim-diels, you are welcome!

As we talked privately, your suggestion to remove the language form solved the problem.

Thanks, looking good. Committed.
