This is my current configuration that adds the meta tags:
{data? <Helmet>
<title>Site- {data.name ? data.name : ""}</title>
<meta charSet="utf-8" />
<meta name="twitter:card" content="summary_large_image" data-react-helmet="true" />
<meta name="twitter:site" content="@user" data-react-helmet="true" />
<meta name="twitter:creator" content="@user" data-react-helmet="true" />
<meta property="og:type" content="website" data-react-helmet="true"/>
<meta property="og:url" content={document.location.href} data-react-helmet="true" />
<meta property="og:title" content={data.name ? data.name : ""} data-react-helmet="true" />
<meta property="og:description" content={data.description?.en?.slice(0, 65) + "..."} data-react-helmet="true" />
<meta property="og:image" content={data.image?.large} data-react-helmet="true" />
</Helmet>
: null}
data is a hook that is populated when the request from the database is done.
Trying on https://cards-dev.twitter.com/validator returns Unable to render Card preview. Any idea how it can be fixed?
