OG Meta Tag Can't detect by Facebook Microdata Debugger

3 weeks ago
This is our client's site https://4u.am/ . Nopcommerce version is 4.2. Open Graph meta tags already added to ProductTemplate.Simple.cshtml. But when I try to debug with facebook microdata debugger, it doesn't detect any opengraph tag and also said id, image_link, title, description etc required field are missing. Here is the result from facebook debugger result
And in my product page these tags are rendered tags
Could anyone tell what is the reason?

If you are using ACL permissions make sure "Guest" role has "Allow Navigation" permission, and then add the "Guest" role to user #2  ([email protected]_engine_record.com): https://www.nopcommerce.com/en/boards/topic/88383/facebook-sharing-open-graph-and-foreign-languages#276201

"Guest" role has already  "Allow Navigation" permission, and already added the "Guest" role to user #2  ([email protected]_engine_record.com). Sharing Debugger (https://developers.facebook.com/tools/debug/)  detects perfectly. But Facebook Microdata debugger (https://business.facebook.com/ads/microdata/debug) detects nothing and it says "The following required field are missing: id, title, price, availability, description, link".
