Blazor JsInterop DOM element reference

Question

We are currently working on a new Blazor Web app, and I'm in charge of porting a few JavaScript libraries that we are going to require. I have a port of gridstack.js working, but I'm not really that familiar with Blazor, and I'm wondering if there is a better way of doing certaing things.

I will be posting code snippets, but if someone wants to look at the whole thing, it is here.

I'm using JsInterop to bring all methods and events of the JavaScript component to Blazor. But certain methods and events return a DOM element (HTMLElement or something of the sort), and sending this from the Js to the Blazor gives me the following error:

//JavaScript code
await interopReference.invokeMethodAsync("AddedFired", items.map(i => { i.el.gridstackNode = undefined; i.el.ddElement = undefined; return i.el; }));

//C# Code
[JSInvokable]
public void AddedFired(ElementReference[] widgets)
{
    Console.Write(widgets);
}

Uncaught (in promise) Error: System.Text.Json.JsonException: __internalId is required.

I tried with an array of IJSObjectReference instead of ElementReference, and I get a similar error

    Uncaught (in promise) Error: System.Text.Json.JsonException: Required property __jsObjectId not found.

As of right now I am sending ids and element querys back and forth, but I was wondering if there is a better way of doing this in blazor.

Thanks in advance!
