Add custom order meta data with price exluding tax in WooCommerce

I'm trying to create a custom meta_key in woocommerce_order_itemmeta table for (unit price excluding tax) to use later.

I added the below code but I keep getting an error on the checkout page, showing only the red mark with 'Internal Server Error'.

Someone who knows where things are going wrong?

// Save custom data to order item meta data

add_action( 'woocommerce_add_order_item_meta', 'unit_price_order_itemmeta', 10, 3 );
function unit_price_order_itemmeta( $item_id, $values, $cart_item_key ) {

        $unit_price  =  wc_get_price_excluding_tax( $product );

        wc_add_order_item_meta( $item_id, '_unit_price', $unit_price , false );

}

In your code you use $product while this is not specified anywhere.

Note: woocommerce_add_order_item_meta hook is deprecated since WooCommerce 3. Use woocommerce_checkout_create_order_line_item instead

So replace:

// Save custom data to order item meta data
add_action( 'woocommerce_add_order_item_meta', 'unit_price_order_itemmeta', 10, 3 );
function unit_price_order_itemmeta( $item_id, $values, $cart_item_key ) {

    $unit_price  =  wc_get_price_excluding_tax( $product );

    wc_add_order_item_meta( $item_id, '_unit_price', $unit_price , false );

}

With

function action_woocommerce_checkout_create_order_line_item( $item, $cart_item_key, $values, $order ) {
    // The WC_Product instance Object
    $product = $item->get_product();
    
    $unit_price = wc_get_price_excluding_tax( $product );
        
    $item->update_meta_data( '_unit_price', $unit_price );
}
add_action('woocommerce_checkout_create_order_line_item', 'action_woocommerce_checkout_create_order_line_item', 10, 4 );
