Well, I’m almost OT, I don’t use Yoast or other kind of SEO plugin, just WP+WooCommerce+iCraft theme and in the Facebook Sharing Debugger I got the same OP’s error.
In my case the problem affect only the images, not the title, not the description. The solution I’ve used works.

Same problem but different context.
I’ve temporarily “fixed” the problem refreshing Facebook after a first scan:
>paste the link in the POST field
>wait for the scan “fail” (no image available)
>delete the field
>refresh the facebook page
>re-paste the link in the POST field
>now should work
