TreeList does not show just inserted row if custom template for edit is enabled

I am using TreeList to edit hierarchical data. I have to use Custom Edit template to create/edit rows. But new row disappears after clicking on Update button in Popup window. I have to refresh page to see new rows. What am I doing wrong?

@(Html.Kendo().TreeList<Models.FlowItemModel>()
    .Name("treelist")
    .Toolbar(toolbar => toolbar.Create())
    .Columns(columns =>
    {
        columns.Add().Field(e => e.FieldType).Width(200).Title("Type");
        columns.Add().Field(e => e.FieldLabel);
        columns.Add().Field(f => f.LineNumber).Width(100).Title("#");
        columns.Add().Field(e => e.DropdownValues).Width(150).Title("DropDown");
        columns.Add().Width(350).Command(c =>
        {
            c.CreateChild().Text("Add child");
            c.Edit();
            c.Destroy();
        });
    })
    .Editable(editable => editable.Move(move => move.Reorderable(true)))
    .Editable(e => e.Mode("popup").TemplateName("CustomTreeListPopup"))
    .Filterable()
    .Sortable()
    .DataSource(dataSource => dataSource
        .Create(create => create.Action("CreateFlowItem", "Configurator").Data("getConfiguration"))
        .Read(read => read.Action("GetFlowItems", "Configurator").Data("getSelectedFlowItem"))
        .Update(update => update.Action("UpdateFlowItem", "Configurator").Data("getConfiguration"))
        .Destroy(delete => delete.Action("DeleteFlowItem", "Configurator"))
        .Model(m =>
        {
            m.Id(f => f.Id);
            m.ParentId(f => f.ParentId).Nullable(true);
            m.Field(f => f.LineNumber);
            m.Field(f => f.FieldLabel);
            m.Field(f => f.FieldType);
        })
    )
    .Events(events =>
     {
         events.DragEnd("onDragEnd");
     })
)

Where is the Kendo.all.js file?

Download 2022.1.301 commercial. The file is 10 MB or so. Same for versions 2022.1.412, 2022.2.510, 2022.2.621, 2022.2.802, and 2022.3.913.

When we get to the 2022.3.1109 commercial download it is no longer included. A 1kb file is there with build statements like importing other files. I need the real file.

Getting error when setting grid datasource: kendo.all.js:311085 Uncaught TypeError: Cannot read properties of undefined (reading 'id')

I have a grid I've created in MVC that is throwing the following error when I set the datasource

kendo.all.js:311085 Uncaught TypeError: Cannot read properties of undefined (reading 'id')

Using version 2022.2.802.545

Here is my grid

@(Html.Kendo().Grid<MyModelName>()
            .Name("event-violations-grid")
            .Columns(columns =>
            {
                //columns.Select().Width(50);
                columns.Bound(s => s.SupplierNumber).Hidden(true);
                columns.Bound(s => s.SupplierName).Width(275);
                columns.Bound(s => s.OldOrderDate).Format("{0:MM/dd/yyyy}").Hidden(true);
                columns.Bound(s => s.OldDeliveryDate).Format("{0:MM/dd/yyyy}").Hidden(true);
                columns.Bound(s => s.NewOrderDate).Format("{0:MM/dd/yyyy}").Hidden(true);
                columns.Bound(s => s.NewDeliveryDate).Format("{0:MM/dd/yyyy}").Hidden(true);
                columns.Bound(s => s.ArrivalDate).Format("{0:MM/dd/yyyy}").Hidden(true);
                columns.Bound(s => s.TransmitTime).Hidden(true);
                columns.Bound(s => s.ExpectedDeliveryTime).Hidden(true);
                columns.Bound(s => s.Action).Width(180);
                columns.Bound(s => s.ActionComments);
            })
            .Sortable()
            .Scrollable(s => s.Height("215px"))
            .HtmlAttributes(new { style = "height:250px;" })
            .Resizable(r => r.Columns(true))
        )

(I know there is a lot of hidden columns there.. I may or may not need them yet)

Then I have some javascript which populates a dataSource and sets to this grid

function getViolations() {
    var vdata = {};
    vdata["stageId"] = _stageId;
    vdata["stores"] = "" + _stores.join(',');
    vdata["supplierNumber"] = _eventRevertData.SupplierNumber;
    vdata["origDeliveryDate"] = kendoDateOnly(_eventRevertData.Start);
    vdata["newDeliveryDate"] = null;

    var dataSource = new kendo.data.DataSource({
        schema: {
            model: {
                fields: {
                    SupplierNumber: { type: "number" },
                    SupplierName: { type: "string" },
                    OldOrderDate: { type: "date" },
                    OldDeliveryDate: { type: "date" },
                    NewOrderDate: { type: "date" },
                    NewDeliveryDate: { type: "date" },
                    ArrivalDate: { type: "date" },
                    TransmitTime: { type: "string" },
                    ExpectedDeliveryTime: { type: "string" },
                    OrderGroup1: { type: "boolean" },
                    OrderGroup2: { type: "boolean" },
                    OrderGroup3: { type: "boolean" },
                    OrderGroup4: { type: "boolean" },
                    OrderGroup5: { type: "boolean" },
                    OrderGroup6: { type: "boolean" },
                    OrderGroup7: { type: "boolean" },
                    OrderGroup8: { type: "boolean" },
                    Action: { type: "string" },
                    ActionComments: { type: "string" }
                }
            }
        },
        transport: {
            read: {
                url: "/MyController/GetViolationsGrid1",
                data: vdata,
                dataType: "json"
            }
        }
    });
    dataSource.fetch(function () {
        let data = this.data();
        console.log(data);
        var grid = $("#event-violations-grid").data("kendoGrid");
        grid.setDataSource(data);
    });
}

This works - my grid displays exactly as I expect, and updates when I call my function (the vdata changes depending on other things)

However, I'm getting this error:

If I open that, I can see that the part of "my" code is here:

Which brings me to here

I have confirmed that I can get as far as line 1228 without issue.. my console.log works and I can see my data.. it seems like it is happening when I'm setting the data source

Any help would be greatly appreciated!

Thanks
