I already viewed many issues that were made over the years and tried some of the ‘strategies’ - one thing I can’t get my head around is that Facebook debugger does not have the same problem, and that Linkedin was working fine until recently despite no code changes.
I've been having this issue too, different tech stack (.net core). I found that URLs with spaces have been a problem, I've advised the content editors to ensure images are all lowercase and hyphenated and that seems to have solved it.
I don't think this is prismic's fault, but I would love to have the ability to automatically enforce a naming convention for images, or at the very least to allow the image to be renamed.
@Phil - Lower case and hyphenated fixed the problem for me too. Is Prismic going to provide any automated solution? It's just another issue that can cause companies quite some problems and could easily be avoided with a technical solution.
