Kendo window with template is producing TS error (TypeError: e.toLowerCase is not a function)

[Brian]

I have a Kendo window:

$("#depDialog").kendoWindow({
    width: "450px",
    modal: true,
    title: "Add Dependency",
    content: {
        template: $('#javascriptTemplate').html()
    },
    visible: false,
    resizable: false,
    actions: [
        { text: "Cancel" },
        { text: "Add", primary: true }
    ]
});

I also have a template:

<script id="javascriptTemplate" type="text/x-kendo-template">
     <div class="row mt-2">
        <div class="col">
            @(Html.Kendo().DropDownList()
                .Name("dep_new")
                .DataTextField("Name")
                .DataValueField("Id")
                .BindTo((System.Collections.IEnumerable)(Model.Applications.ToList()))
                .SelectedIndex(0)
                .ToClientTemplate()
            )
        </div>
        <div class="col">
            @(Html.Kendo().TextBox()
                .Name("dep_notes_new")
                .HtmlAttributes(new { style = "height: 38px;" })
                .ToClientTemplate()
            )
        </div>
    </div>
</script>

I have an empty div to load the template:

<div id="depDialog"></div>

I tried using a dialog (hence the naming) but I couldn't get it to work.  Now I'm using a window, and I'm getting the following TS error:

kendo.all.js:96132  Uncaught TypeError: e.toLowerCase is not a function
    at kendo.all.js:96132:1
    at Function.map (jquery-3.7.0.min.js:2:3967)

    at e.fn.<computed> [as kendoWindow] (kendo.all.js:3740:1)

The error line points to the kendoWindow initialization.  Thoughts?

Hello, Brian,

The Window doesn't have "actions" configuration. Please remove that from the code for the component in order to avoid the error.

Let me know how that goes.

Hi Martin,

Unfortunately, the error persists after removing the 'actions' as well.

I'm going to use the default grid edit instead of a custom popup window to edit to resolve.

Thanks,
