I've got a content type which references a taxonomy vocabulary via a multi-value field.
When I try to create a view of my content and add a taxonomy field to my view I get the following error in the console:
An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging information follows. Path: /admin/structure/views/ajax/add-handler/mycontent/default/field StatusText: OK ResponseText: Error: Unsupported operand types in Drupal\views\Plugin\views\field\FieldPluginBase->getElements() (line 314 of /var/www/html/core/modules/views/src/Plugin/views/field/FieldPluginBase.php).
