Hey there. For all the sites I've built I have always had this Open Graph error.
First of all here https://developers.facebook.com/tools/debug it shows this
even though I always fill all the fields
So in reality it never works whenever I publish the site for the first time and I have to maunually double click "Scrape again" in FB debugger. Definitely not something nice to do for large sites, especially for dynamic content.
Also would be nice to have possibility to set OG Image URL from a Link field in collection, not only Image field.
