Django/Wagtail : InvalidFilterSpecError at /blog/article-blog-page/ when i refresh my Article Blog Page

在按照 Wagtail CMS: How to subclass Wagtail Pages 的教程进行操作时,我在刷新文章博客页面时遇到了错误。我正在使用调试工具栏 3.2.2、Python 3.9.6、Wagtail 核心 2.14.1、Taggit 1.5.1 和 Django 扩展 3.1.3。

应该是

{% image self.intro_image fill-1400x400 as intro_img %}

(注意 'fill' 之后的 -,而不是 space)
