Button click not refreshing the page it throws Uncaught ReferenceError: is not defined

I have a button on the page, the button logic works but it doesnot refresh the page. Button is on the table to add items in to the cart

            <td>
                <row>
                    <column>
                        <input type="text" style="text-align:center" id="@("quantityReq"+@item.InventoryId)" name="quantityReq" value="@item.QuantityReq" size="2" /> &nbsp;
                    </column>
                    <column>
                        <input type="hidden" id="@("customer"+@item.InventoryId)" name="customerID" value="@Model.CustomerData.CustomerId" />
                        <input type="hidden" id="@("inventory"+@item.InventoryId)" name="invetoryID" value="@item.InventoryId" />
                        <br />
                        <a href="#" id="buyNow" data-id="@item.InventoryId">Add to Cart</a>
                </row>
            </td>

Below is the script for the above button

<script type="text/javascript">
            $(document).ready(function () {
                $(document).on("click", "#buyNow", (function (e) {
                    e.preventDefault();
                    e.stopImmediatePropagation();
                     var id=$(this).data("id");
                    onBuyNow(id);
                }));

                function onBuyNow(id) {
                    var quantityReq = $("#quantityReq"+id).val();
                    var customerId = $("#customer"+id).val();
                    var data = {
                        customerID: customerId,
                        quantityReq: quantityReq,
                        invetoryID: id
                    };

                    $.ajax({
                        type: 'POST',
                        url: '@Url.Action("OrderItem", "Inventories")',
                        
                        data: data,
                        dataType: "json",
                        success: function (result) {
                            if (result !== "")
                            {
                                if (result.available == "Quantity0")
                                    $("#errorMessage" + result.inventoryId).val("Enter a valid Quantity");
                                else
                                    $("#errorMessage" + result.inventoryId).val(`Only ${result.available} available`);
                            }
                            else {
                                var url = '@Url.Action("Index", "Inventories")';
                                alert(url);      
                                var roomId = @HttpContextAccessor.HttpContext.Request.Query["rmName"]
                                alert(roomId);
                                    window.location.href = `${url}?custID=${customerId}&rmName=${roomId}&success=true`;  
                            }
                        },
                        error: function (error) {
                            alert(error);
                        }
                    });
                    };
                });
        </script>
    }

I have the OrderItem method on the Inventories controller which takes care of the adding the item to cart and dealing with the updating the quantity if the result is an empty string is not refreshing the page. I can see the fisrt alert(url) shows up but not the alert(roomId).The current URL of the page is https://localhost:xxxxx/Inventories/Index/56?custID=56&rmName=A1 I am not sure why @HttpContextAccessor.HttpContext.Request.Query["rmName"] is not working here. I was hoping the click of the button if the result is empty string it will return the URL like https://localhost:xxxxx/Inventories/Index/56?custID=56&rmName=A1&success=true.

after clicking the button it just stays like below

enter image description here

I finally see the error on the console like

enter image description here

Can anyone please suggest what is that I am missing

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
