Problem/Motivation
Enable rest module, go to 'admin/config/services/rest', and save content exposed as web service.
Go to 'entity/node/1', I get error:Fatal error: Unsupported operand types in D:\Apache\drupal8\core\modules\jsonld\lib\Drupal\jsonld\JsonldEntityNormalizer.php on line 37
By the way, I'm using a win7 system.
