The following code isn't working. And it says "Function id was called incorrectly" <a href="http://www.amazon.com/gp/product/<?php echo get_post_meta( $product->id , '_amzASIN', true );?>/?tag=solomon09-20" class="button" target="_blank">MORE INFORMATION</a> Wordpress 6.6.1, PHP 8.2 The code was working with previous versions of woocommerce, wordpress, and on PHP 7.2 etc. Not working with latest versions. The code extracts amazon ASIN for a particular product from its metadata, and inserts in the above to generate a url. This is the complete error- Notice: Function id was called incorrectly. Product properties should not be accessed directly.
