有后端过滤器列表问题

Question

对于我的两个发行版，在过滤任何后端模型列表时遇到一个独特的问题。他们有不同的插件。两者之间最常见的事情是它们具有我首先使用Builder插件创建的自定义插件。它们还托管在不同的Linux服务器上。

错误是：

Symfony\Component\Debug\Exception\FatalThrowableError: Type error: Return value of Backend\Widgets\Lists::putUserPreference() must be an instance of Backend\Traits\void, none returned in /home/deltarv/public_html/modules/backend/traits/PreferenceMaker.php

这里是日志跟踪：

• 内部版本为458。

• 我有一些第三方插件和一些我自己创建的插件。没有其中已过时。

• 这些是唯一存在筛选列表问题的发行版领域。我的其他带有类似第三方和自定义插件的发行版也可以正常工作。

• 我可以创建和更新记录，并对记录中的记录进行排序列表视图。

此错误与void datatype有关。它是在PHP 7.1中引入的。在较低的PHP版本中导致错误问题。
