If they exist but you get an error when you access try to directly access them, then it's not a problem with HikaShop. It's probably your web server configured to only allow the download of some file extensions and the webp extension is not included in the list.
So you need to add it. It should be either in the configuration of the web server or the htaccess of the website.
