传递给 EntityViewBuilder 的参数 1 必须实现接口,给定为 null
Argument 1 passed to EntityViewBuilder must implement interface, null given
在我的 Drupal 项目中我有这个错误:
Recoverable fatal error: Argument 1 passed to
Drupal\Core\Entity\EntityViewBuilder::view() must implement interface
Drupal\Core\Entity\EntityInterface, null given, called in
/Users/team1/workspace/ga_p/modules/field_collection/src/Plugin/Field/FieldFormatter/FieldCollectionItemsFormatter.php
on line 33 and defined in Drupal\Core\Entity\EntityViewBuilder->view()
(line 110 of core/lib/Drupal/Core/Entity/EntityViewBuilder.php). I do
not know if it's from having created multiple fields
(fieldCollections)
但我不知道如何消除这个错误。
Drupal 版本:8.3.4
试试这个补丁
