Not sure if this is a bug, but I wanted to add some debug into an HTML comment in my page.html.twig file. I added <!-- type={{node.type}} --> but I get:

Uncaught PHP Exception Exception: "Object of type Drupal\Core\Field\EntityReferenceFieldItemList cannot be printed." at /www/cn8/core/lib/Drupal/Core/Template/TwigExtension.php line 443

It took me a while to track down since I was sure this would work. Shouldn't EntityReferenceFieldItemList have a toString() function for this purpose?

  • I just worked out that I can write node.type.target_id and get the content type as a string, but still don't understand why node.type doesn't output something, but crashes... – Nic Sep 15 '16 at 8:23

node.type is a reference to the node type entity. You can get the id of the content type with target_id, as you have mentioned in the comment. For debugging this might be OK, but most times you want to get the label, which is nicely formatted and translatable:

{{ node.type.entity.label }}
