Open Graph for Jekyll not showing as expected

Question

Knowing little about programming, I followed the descriptions on Opengraph link previews in Jekyll and https://jekyll.github.io/jekyll-seo-tag/installation/ , trying to set up Open Graph preview for my website.

I can see property="og:title" etc tags on the website pages' HTML code as a result.

However, when sharing a link on Telegram, there's no preview for most of the pages except for the home page https://www.lintj.com/

To check my code: https://github.com/gclintj/test

Per kalehmann,

First of all, you don't have the minima gem in your dependencies, try bundle add minima

Then you have <link rel="canonical" href="http://localhost:4000/"> in https://github.com/gclintj/test/blob/gh-pages/_layouts/default.html#L24. This prevents your preview from being displayed. You can safely remove this line, as the jekyll-seo-tag plugin will add it again.

Following kalehmann's instructions above, the problem has been solved.
