Add support for Field Collection

Just installed this on a clean D8 install, attempted to create a visibility dependency on a Select List value and I get the following error:
"The website encountered an unexpected error. Please try again later."

The dependency is on a field inside a field collection group. It looks like it creates the dependency but won't let me in to edit it.

The log details are:
"Drupal\Component\Plugin\Exception\PluginNotFoundException: The "" entity type does not exist. in Drupal\Core\Entity\EntityTypeManager->getDefinition() (line 133 of /var/www/html/core/lib/Drupal/Core/Entity/EntityTypeManager.php)."

Any help would be appreciated, I'm not really a PHP dev so debugging this is well beyond my realm. Thanks!
