Facebook开放图形og：图像由Facebook查看但未显示

Question

我已经阅读了很多关于该主题的SO帖子但是我的问题仍然存在：Facebook将我的元标记视为原始标记，但在打开的图形显示期间不显示或包含图像。这是我试图在Facebook上发布的网址：

https://holyunions.com/govt-releases-gh-cent-465-million-for-start-of-one-district-one-factory-project-general-language-en-article-118

这是我输出的代码

<meta property="og:title" content="Govt releases GH¢465 million for start of one-district-one factory project - General :. Twum Barimah" />
<meta property="og:type" content="article" />
<meta property="og:url" content="https://holyunions.com/govt-releases-gh-cent-465-million-for-start-of-one-district-one-factory-project-general-language-en-article-118" />

og图像属性已明确定义Facebook after displaying them as tags，仍然无法获取图像，也不会显示图像，也不会显示打开的图形属性中的描述。

如何显示facebook看作网址的图片？
