Datatable load via proxy

Webix JS
1

Hi,

I’m trying to load a datatable in a JET page via proxy.

if I use DT.load(“list->list”) page loads fine,
if I use DT.load(ProxList ) the page loads but if I come back to the page it hangs. no errors displayed.
I have debug turned on.

webix.proxy.List = {
    $proxy: true,
    load: async function (view, params) {

        let ResponseJSON = await webix.ajax().post("list");
        let response = ResponseJSON.json();

        return response || [];
    },
    save: function (view, update) {
        update.clientId = this.clientId;
        update.key = this.key;
        update.data = webix.stringify(update.data);
        update = webix.stringify(update);

        let parsedData = { msg: update, type: "message" };
        broadcastChannel.postMessage(parsedData);
    }
}

ProxList = webix.proxy("List", serverHost + "/ws", {
            key: "List", clientId: clientId
        });
