Duplicate per-product shipping extension information - WooCommerce - php

Question

on my wordpress site I have WooCommerce and the WooCommerce per product shipping extension (https://docs.woocommerce.com/document/per-product-shipping/). I currently have an issue, this is that whenever I duplicate a woocommerce product the per-product shipping information is not copied. I have tried to find a solution for this and have got the following code however I have not been able to get it work, can anyone see what is going wrong in the following
add_action( 'woocommerce_product_duplicate', 'wdm_duplicate_pps_entries',10,2);
function wdm_duplicate_pps_entries( $new_id, $post) {
global $wpdb;
$id = isset( $_REQUEST['post'] ) ? absint( $_REQUEST['post'] ) : '';
if(!empty($id)) {
$query = "Select * From " . $wpdb->prefix . "woocommerce_per_product_shipping_rule
Where product_id = '" . $id . "'";
$result = $wpdb->get_results($query);
$table_name = $wpdb->prefix . "woocommerce_per_product_shipping_rule";
foreach($result as $single_result) {
$data = array('product_id' => $new_id, 'rule_country' => $single_result->rule_country, 'rule_state' => $single_result->rule_state,'rule_postcode' => $single_result->rule_postcode,'rule_cost' => $single_result->rule_cost,'rule_item_cost' => $single_result->rule_item_cost,'rule_order' => $single_result->rule_order);
$wpdb->insert($table_name,$data);
}
}
}
This is an example of the additonal info I am trying to copy -

function wdm_duplicate_pps_entries( $new_id, $post) {
global $wpdb;
$id = isset( $_REQUEST['post'] ) ? absint( $_REQUEST['post'] ) : '';
if(!empty($id)) {
$query = "Select * From " . WC_PRODUCT_VENDORS_PER_PRODUCT_SHIPPING_TABLE . "
Where product_id = '" . $id . "'";
$result = $wpdb->get_results($query);
$table_name = WC_PRODUCT_VENDORS_PER_PRODUCT_SHIPPING_TABLE;
foreach($result as $single_result) {
$data = array('product_id' => $new_id, 'rule_country' => $single_result->rule_country, 'rule_state' => $single_result->rule_state,'rule_postcode' => $single_result->rule_postcode,'rule_cost' => $single_result->rule_cost,'rule_item_cost' => $single_result->rule_item_cost,'rule_order' => $single_result->rule_order);
