My social card struggle with React Helmet

I've been fighting against react-helmet for a while now, and debugging the issue has left me with conflicted views. My SEO knowledge is a bit basic, that might explain why I'm struggling to catch the issue.

I'll break down the article into 2 parts:

  1. The set up of the site
  2. The problem & debugging attempts

1. Site setup

The site is build using GatsbyJS, and has an SEO component that makes use of react-helmet, which is available as a GatsbyJS plugin. There are 5 'hard-coded' pages (404, index, blog, about, contact), and the blog posts are programmatically generated (explained in the Gatsby docs here). The tutorial I followed to implement the SEO component is taken from Gatsby docs.

Code snippets

The seo component can take the following props:

const SEO = ({ title, description, image, article }) => { ... }

And it also has fallback values, incase I don't pass down all props:

const {
  } = site.siteMetadata

siteMetadata (containing default/fallback values) in the SEO component comes from the static graphql query:

const query = graphql`
  query SEO {
    site {
      siteMetadata {
        defaultTitle: title
        defaultDescription: description
        siteUrl: url
        defaultImage: image
        twitterUsername : author

the query gets the data from gatsby-config.js:

module.exports = {
  siteMetadata: {
    title: `Goosebumps Collective`,
    titleTemplate: "%s ยท Goosebumps Collective",
    description: `Freelance Web Development & Curated Music`,
    url: "https://goosebumps.co.zw",
    image: `/goose.png`,
    author: `@txndai`,

Default values & react-helmet structure:

const seo = {
    title: title || defaultTitle,
    description: description || defaultDescription,
    image: `${siteUrl}${image || defaultImage}`,
    url: `${siteUrl}${pathname}`,

  return (
    <Helmet title={seo.title} titleTemplate={titleTemplate}>
      <meta name="description" content={seo.description} />
      <meta name="image" content={seo.image} />

      {seo.url && <meta property="og:url" content={seo.url} />}

      {(article ? true : null) && <meta property="og:type" content="article" />}

      {seo.title && <meta property="og:title" content={seo.title} />}

      {seo.description && (
        <meta property="og:description" content={seo.description} />

      {seo.image && <meta property="og:image" content={seo.image} />}

      <meta name="twitter:card" content="summary_large_image" />

      {twitterUsername && (
        <meta name="twitter:creator" content={twitterUsername} />

      {seo.title && <meta name="twitter:title" content={seo.title} />}

      {seo.description && (
        <meta name="twitter:description" content={seo.description} />

      {seo.image && <meta name="twitter:image" content={seo.image} />}

export default SEO

2. Problem + Debugging attemps

You'd think I have all my bases covered. When I share links to any page on the website, it remains as just a text link, and no card appears. I've tried Twitter, WhatsApp, & Facebook.

When I submit a url on Twitter Card Validator, the log I receive is:

INFO:  Page fetched successfully
INFO:  3 metatags were found
ERROR: No card found (Card error)

I've been receiving that error from the get go (a good couple of weeks at the time of writing), and the case remains the same, as I have just tried this url.

Other social card validators

I've also tried iframely, socialsharepreview, metatags.io - all with fairly positive results, indicating that there's a title, description, & image (all open graph).

The <head> element of all pages seem to have all the meta required, so I can't quite tell where my main issue lies.
