TYPO3 9 Extbase EXT FileReference 的 originalResource 始终为 NULL。为什么？

Question

我正在开发自己的扩展。在此扩展中，可以将图像添加到内容元素。在后端查看一切正常。在数据库中，sys_file 通过 sys_file_reference 对我的数据库 table 的引用看起来也不错。
但是当我在模板中放置 <f:debug>{_all}</f:debug> 时，File 的 originalResource 为 NULL.

有人能告诉我，我错过了什么吗？

这是我的扩展程序的一些代码： ext_tables.sql

这是 f:debug 的输出：

弃用日志：

Answer 1

直接调用debug-ViewHelper中的originalResource即可：

<f:debug>{image.originalResource}</f:debug>
