That's not doable at the moment. You can set message properties if you use the underlying php-amqplib library that the bundle depends on

rabbitmq set message Properties php
I have that error in the code below. What's wrong ? I have no ideas left.

missing ] after element list
   [object XMLHttpRequest]

   $(function () {
            setInterval($.post('/Sale/UpdatePrice', 
                                {SaleId : @Model.Id},
                                function(data){
                                    $('#mPrice').val(data);    
                                }
                            )
                        ,5000); //refresh every 5 seconds
        });


    C#
    public JsonResult UpdatePrice(int SaleId)
    {
        ...

       return Json(NewPrice, JsonRequestBehavior.AllowGet); //NewPrice is a decimal 
                                                              number
    }
