Issue With Open Graph Tags And Nuxt.js (prod?)

I integrated OpenGraph tags into my Nuxt.js app, following the instructions from their SEO documentation at https://nuxtjs.org/examples/seo-twitter-og

I'm setting tags from a child component using the SocialHead component. The contents of this component are:

<template>
  <span v-if="false" />
</template>

<script>
export default {
  props: {
    title: {
      type: String,
      default: '',
    },
    description: {
      type: String,
      default: '',
    },
    url: {
      type: String,
      default: '',
    },
    image: {
      type: String,
      default: '/images/hero/brain-og.png',
    },
  },
  head() {
    return {
      title: this.title,
      meta: [
        {
          hid: 'og:title',
          name: 'og:title',
          content: this.title.replace(' - M.academy', ''),
        },
        {
          hid: 'description',
          name: 'description',
          content: this.description,
        },
        {
          hid: 'og:description',
          property: 'og:description',
          content: this.description,
        },
        {
          hid: 'og:url',
          property: 'og:url',
          content: process.env.baseUrl + this.url,
        },
        {
          hid: 'og:type',
          property: 'og:type',
          content: 'website',
        },
        {
          hid: 'og:image',
          property: 'og:image',
          content: process.env.baseUrl + this.image,
        },
        {
          hid: 'og:image:secure_url',
          property: 'og:image:secure_url',
          content: process.env.baseUrl + this.image,
        },
        {
          hid: 'og:image:alt',
          property: 'og:image:alt',
          content: this.description,
        },
        {
          hid: 'twitter:title',
          name: 'twitter:title',
          content: this.title.replace(' - M.academy', ''),
        },
        {
          hid: 'twitter:card',
          name: 'twitter:card',
          content: 'summary_large_image',
        },
        {
          hid: 'twitter:image',
          name: 'twitter:image',
          content: process.env.baseUrl + this.image,
        },
        {
          hid: 'twitter:description',
          name: 'twitter:description',
          content: this.description,
        },
        {
          hid: 'twitter:site',
          name: 'twitter:site',
          content: '@mdote: 'twitter:card',
          content: 'summary_large_image',
        },
        {
          hid: 'twitter:image',
          name: 'twitter:image',
          content: process.env.baseUrl + this.image,
        },
        {
          hid: 'twitter:description',
          name: 'twitter:description',
          content: this.description,
        },
        {
          hid: 'twitter:site',
          name: 'twitter:site',
          content: '@mdotacademy',
        },
        {
          hid: 'twitter:creator',
          name: 'twitter:creator',
          content: '@markshust',
        },
      ],
    }
  },
}
</script>

I'm using Google Chrome's "Open Graph Preview" extension and locally, they all appear to work and preview correctly:

However, when I deploy these updates to production and check again, all of the Open Graph preview tools I use do not seem to find the tags:

I have also tested LinkedIn's & Twitter's open graph preview tools at:

• https://www.linkedin.com/post-inspector/
• https://cards-dev.twitter.com/validator

I'm a bit stuck, because the tags appear when viewing the page source, and also using a tool like https://www.opengraph.xyz/ -- but not using the actual LinkedIn & Twitter verification tools.

The page I tested out is https://m.academy/courses/build-12-factor-nodejs-app-docker/

At the end, getting rid of prerender.io was enough to fix the SEO issue, since the configuration was properly done.
