We have https://fiftieth.netlify.app/ using the pre-render service. The URL unfurls fine, sometimes, other times it doesn’t. Would really love some help (thanks to your email support for helping us with another issue related to this also!).
- Twitter works https://cards-dev.twitter.com/validator (sorry I can’t deeplink to the preview)
- Facebook doesn’t work with the same url Sharing Debugger - Facebook for Developers
- LinkedIn doesn’t work with the same url Post Inspector
And Slack and Discord work fine (IIRC, one of these crawls the completely rendered page anyway)
I am really confused because twitter works. I reviewed the markup that facebook has and it looks like window.prerenderReady might be getting called too early… but that wouldn’t explain why twitter works and facebook doesn’t bcs surely they are crawling the same pre-rendered page?
I am going to try locally debugging it to go further, but if anyone can help I’d really appreciate it.
Many thanks <3
