Warning: Undefined array key "label" in Drupal\entity_display_json\Controller\EntityDisplayJsonController->processEntity() (line 150 of /modules/contrib/entity_display_json/src/Controller/EntityDisplayJsonController.php)
1. Ensure the Links core field is visible in the Default view mode of any content type.
2. Navigate to the endpoint of the node of the same content type above using the /ejson/node/ path and you will see there is no label key.
