参数1传递给EntityViewBuilder必须实现接口，NULL给出

Question

在我的Drupal项目中，我有这样的错误：

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)

但我不知道如何删除这个错误。

Drupal的版本：8.3.4

Answer 2

我执行

patch -p1 < bin/patchs/fieldCollection.patch

输出：

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:

-------------------------- |diff --git a/src/Plugin/Field/FieldType/FieldCollection.php

在这一点上，我发现我的电脑 “FieldCollection.php” 的文件上，把绝对路径

在这一点上，我在我的电脑上找到 “FieldCollectionEmbedWidget.php” 文件，并将绝对路径

Hunk #1 succeeded at 111 (offset 7 lines).

但是问题仍然存在

Answer 3

我试图通过GIT

运行补丁

[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'.

因为它没有工作，我尝试过这样的：

[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

Hunk #1 FAILED at 183.

Hunk #2 FAILED at 227.

2 out of 2 hunks FAILED -- saving rejects to file src/Plugin/Field/FieldType/FieldCollection.php.rej

patching file src/Plugin/Field/FieldWidget/FieldCollectionEmbedWidget.php

Reversed (or previously applied) patch detected! Assume -R? [n]

我不明白发生了什么。

请问，我该如何解决这个问题？

谢谢
