參數1傳遞給EntityViewBuilder必須實現接口，NULL給出

在我的Drupal項目中，我有這樣的錯誤：參數1傳遞給EntityViewBuilder必須實現接口，NULL給出

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)

但我不知道如何刪除這個錯誤。

Drupal的版本：8.3.4

我不知道很好，他們如何把補丁。你能否告訴我如何應用它的細節？謝謝 – Javier

我執行

patch -p1 < bin/patchs/fieldCollection.patch

輸出：

can't find file to patch at input line 5

Perhaps you used the wrong -p

or --strip option? The text leading up to this was:

該修補程序未應用 - 您需要在此運行命令/ Users/team1/workspace/ga_p/modules/field_collection/...否則手動掛起線路，重建緩存並重試。 –

我在該文件夾中運行該命令並應用了補丁程序。但問題仍然存在...... – Javier

您重建了緩存嗎？ –

我試圖通過GIT

運行補丁

[email protected]:[~/workspace/ga_p/modules/field_collection]: (master): git apply -v /Users/team1/workspace/ga_p/bin/patchs/fieldCollection.patch

Skipped patch 'src/Plugin/Field/FieldType/FieldCollection.php'.

Skipped patch 'src/Plugin/Field/FieldWidget/FieldCollectionEmbedWidget.php'.

因爲它沒有工作，我嘗試過這樣的：

[email protected]:[~/workspace/ga_p/modules/field_collection]: (master): patch -p1 < /Users/team1/workspace/ga_p/bin/patchs/fieldCollection.patch

patching file src/Plugin/Field/FieldType/FieldCollection.php

我不明白髮生了什麼。

請問，我該如何解決這個問題？

謝謝
