I was following the steps to set up the REST server:
- Enabled rest module.
- Added rest.settings.yml at sites/default/files/config_somehash/staging/rest.settings.yml as per the above guide.
- Open admin/config/development/sync and hit Sync all.
The following error raises:
Fatal error: Call to a member function delete() on a non-object in /home/juampy/projects/drupal8/core/lib/Drupal/Core/Config/Entity/ConfigStorageController.php on line 530
The entity that is not found and which causes the error has $name as entity.display.custom_block.basic.default con and $id as custom_block.basic.default
