Currently my site (made in Laravel) only displays title and url when shared, even though the og:image and og:description tags are present. I use the laravel SeoTools package, and as far as I can see, all the tags display in the head tag successfully. Facebook debugger tells me the server gives a 418 error, but I have not been able to find any way to address it. When I press the "see what the scraper sees" button, the whole page is blank.
