Error when using fee (bad value)

Hello,

I am working on a Webshop that got a custom fee in Woocommerce.

The fee gets applied via the function.php file and if activated, Klarna creates an error on the checkout page called: Bad value: order_lines[4].total_tax_amount

After research the error states that the total-cart-amount does not match the total-amount to pay via Klarna.

My question: Can I disable this background check from the Klarna Plug-In? Or is it possible to flag that cart-fee so Klarna doesn’t throw an error?

Below the used “custom” fee code in functions.php:

add_action('woocommerce_cart_calculate_fees', function() {
    if (is_admin() && !defined('DOING_AJAX')) {
        return;
    }
    $cart_total_price = WC()->cart->subtotal;
    if($cart_total_price < 10){
        WC()->cart->add_fee(__('Verpackungs-/Servicepauschale', 'txtdomain'), 1); // source: https://woocommerce.wp-a2z.org/oik_api/wc_cartadd_fee/
    }
    
});

Thanks for any help!
