For everyone, still having this problem, and for me, none of the published solutions have been developed.
I had a similar problem. The image displayed correctly in all other share dialogs. Only WhatsApp was unable to display the image, even if the facebook debugger correctly had the og: image tag.
Solution that worked for me: I am using firebase. For downloaded content in the repository, you get a unique download URL with a media token. Something like:
https://firebasestorage.googleapis.com/v0/b/XXXX.XXXXXXX.com/ ? alt = media & token = YYYYYYYY-YYYYYYYYYYYYYYYYYYYYYYYYY
I used this URL in the og: image meta tag. It worked on Facebook, etc., but it seems like WhatsApp was not able to download the image from this URL. Instead, you need to include the image in the project directory and use this link for the og: image tag. Now it works correctly on WhatsApp.
Before (does not work in WhatsApp, but facebook, etc.)
<meta property="og:image" itemprop="image" content="https://firebasestorage.googleapis.com/v0/b/XXXX.XXXXXXX.com/your_image?alt=media&token=YYYYYYYY-YYYYYYYYYY-YYYYYYYYYYYYY">
After (now works in all checked general dialogs, including WhatsApp)
<meta property="og:image" itemprop="image" content="https://domain_name/path_to_image">
Hope this can help some of you :)
