I saw warning messages like following after having module 'unique_field' installed:

User error: "bundle" is an invalid render array key in Drupal\Core\Render\Element::children()

The reason is that the variable $form['bundle'] injected is not a valid Drupal 8 form element and can't be rendered. To fix/bypass the warnings, I changed variable name from $form['bundle'] to $form['#bundle']. It might not be a perfect solution but it works.

Patch file attached.
