getting worse, undefined errors

function yith_wapo_set_js_variables() {
    ?>
    <script type="text/javascript">
        document.addEventListener("DOMContentLoaded", function() {
            // Ensure yith_wapo exists to avoid reference errors
            if (typeof yith_wapo === 'undefined') {
                window.yith_wapo = {}; // Initialize as an empty object if it doesn't exist
            }

            // Set the desired properties
            yith_wapo.woocommerce_currency_symbol = "$";
            yith_wapo.woocommerce_currency_pos = "left";
            yith_wapo.total_thousand_sep = ",";
            yith_wapo.decimal_sep = ".";
            yith_wapo.num_decimal = 0;

            // Log the object to confirm (optional)
            //console.log(yith_wapo);
        });
    </script>
    <?php
}
add_action('wp_footer', 'yith_wapo_set_js_variables', 100);

my developer had to implement the above fix, after this latest YITH terrible plugin version update.
