I debug a shared webpage link in facebook debugger and I get a 200 code as result. The Facebook Debugger can't show the image attached and also it doesen't show while sharing the URL. On Whatsapp and Telegram it works fine. The og:image is present and the image url is working properly. The debugger gives me the warning that I have not a fb:app_id but I don't have a Facebook app, also other links on my site work fine but I could not identify the difference. What can I do?
