plugin just is not outputting og:image

[rkaufman13]

My frontmatter:

---
layout: post
title: "title"
categories: things-i-learned
excerpt_separator: <!--more-->
description: description
image: /assets/rabbit_on_computer.jpg
---

Have also tried:

image:
    path: /assets/rabbit_on_computer.jpg

Either way, bundle exec jekyll build does not output files with an og:image tag in my page's metadata. The other og fields generate correctly. I'm not sure what else I could be doing wrong?

Looks like I've got v 2.8.0 of the plugin and jekyll 3.9.0.
