How to edit a property when creating an order?

Question

1C-Bitrix

Hello !

I'm trying to edit a property when creating an order:

use Bitrix\Main; 
Main\EventManager::getInstance()->addEventHandler(
    'sale',
    'OnSaleOrderBeforeSaved',
    'onBeforeOrderSaveHandler'
);

function onBeforeOrderSaveHandler(Main\Event $event)
{

    /** @var \Bitrix\Sale\Order $order */
    $order = $event->getParameter('ENTITY');
    $oldPrice = $order->getField('PRICE');
    $newval = CCurrencyRates::ConvertCurrency($oldPrice, "EUR", "RUB");
    $newPrice = round($newval);
    $propertyCode = 'new_price';

    /** @var \Bitrix\Sale\PropertyValue $property */
    foreach ($order->getPropertyCollection() as $property) {
        if ($property->getField('CODE') === $propertyCode) {
            $property->setValue($newPrice);
        }
    }

    $saveResult = $order->getPropertyCollection()->save();
}

But when creating a new order, I get an error:


A new order is not created, it just hangs in an endless loading. An error in the console complains about this function:

function submitOrder(form) {
$('.js_ord').hide();
        $('#preloader').show();
        var pric = $("#price_delivery_id").val();
        if($("#deliveryTypesBlock .selected input[name='DELIVERY_ID']").data("ourdelivery") != 1){
          $("#price_delivery_id").val(0);
        }
        if($('[name="DELIVERY_ID"]:checked').val() == 2){

            $("#price_delivery_id").val(pric);
            $("input[name='ORDER_PROP_22']").val(pric)

        }
        var fname = $("input[name='ORDER_PROP_8']").val();
        var lname = $("input[name='ORDER_PROP_9']").val();
        var email = $("input[name='ORDER_PROP_2']").val();

        $.ajax({
            method: "POST",
            url: "/ajax/mailchump_integrate.php",
            data: { email: email, fname: fname, lname: lname }
        });

            var err=false;
            $('.pane.last').find('.pane-errors ul').empty()
            $('.pane').each(function(){
                var $pane = $(this);
                errors = validatePane($pane, "required")
                if(errors.length) {
                    for(var i = 0, l = errors.length; i < l; ++i) {
                        $('.pane.last').find('.pane-errors ul').append($("<li>" + errors[i] + "</li>"));
                        err =true;
                    }
                }
            })
            if(err)return false;
        $( '#price_delivery_id' ).val( 0 );
        var data = $(form).serialize();

        $.ajax({
            url: $(form).attr('action'),
            data: data,
            type: "post",
            success: function(response) {
                console.log(response);

                 if(response['order']["REDIRECT_URL"]) {
                    location.href = response['order']["REDIRECT_URL"];
                 }

                var propertyErrors = response['order']["ERROR"]["PROPERTY"];

                if(propertyErrors) {
                    for(var i in propertyErrors) {
                        $('.errors ul').append($("<li>" + propertyErrors[i] + "</li>"))
                    }
                }
            }
        })
    }

Tell me what's the problem?

Understood, can be useful to someone. In the settings of the online store module, it was necessary to enable the processing of obsolete events. After that everything worked.
