I have a NextJS 15 app deployed on Vercel. From what I can tell, the OpenGraph metadata is set properly via the static metadata property and dynamic generateMetadata function on all pages of my app (except the error page for now). However, Vercel’s built-in Open Graph preview tab shows no OG metadata.
Let’s use this preview deployment as an example: https://godsreveal-n4ooql289-johnny-woodtkes-projects.vercel.app/
As you can see, this third-party OG metadata analyzer shows all proper metadata: OpenGraph - Preview Social Media Share and Generate Metatags - OpenGraph
But the following screenshot of Vercel’s Open Graph preview shows that no OG metadata is set:
This same issue occurs in my production deployment as well.
