Error on amp page that serve from google cache

Hi
Thank you for the great rating plugin.

The plugin runs fine on both regular and amp pages. But for the amp page that serves from the google cache (https://www.google.com/amp/s/mysite.com/cat/post-url/amp/) when the rating is clicked it will display the error “There was an error rating this post!”.

when I inspect element in chrome browser there is an error:

Access to fetch at ‘https://mysite.com/wp-admin/admin-ajax.php has been blocked by CORS policy: The ‘Access-Control-Allow-Origin’ header contains the invalid value ‘*.ampproject.org’. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.
