Programmatically create a comment form for a node

I’m trying to port a theme from Drupal 6 to Drupal 8, and I find code like the following.

$edit = array(); $edit['nid'] = $node->nid; $form = drupal_get_form('comment_form', $edit));

How do I load the form in Drupal 8? I get the following error:

Fatal error: Call to a member function getEntityTypeId() on null in /www/site/core/lib/Drupal/Core/Entity/EntityForm.php on line 77

The line causing the error is the following one:

Drupal::formBuilder()->getForm('DrupalcommentCommentForm');

I can’t work out how to pass the node object to the form builder. How can I do it?
