Getting an error while fetching the data and bind it in the Tree table

Question

Hi All,
I am getting an error "A navigation paths parameter object has to be defined - " while fetching the data and bind it in the Tree table.
Please find the code and screenshot below
var oModel = new sap.ui.model.odata.ODataModel("../../../XXXX.xsodata/", true);
var oTable = sap.ui.getCore().byId("table");
oTable.setModel(oModel);
oTable.bindRows({
    path: "/Parent",
    parameters: {expand: "Children"}
Can anyone please give me a suggestion to rectify this?
Thanks in Advance,

Hi All,
Please see the below code. It works fine for me.
var oController = sap.ui.controller("member_assignment");
var oModel = new sap.ui.model.odata.ODataModel("../../../services/XXXX.xsodata/", true);
var Context = "/PARENT?$expand=ASSIGNEDCHILD&$select=NAME,ID,ASSIGNEDCHILD/NAME,ASSIGNEDCHILD/ID,ASSIGNEDCHILD/PARENT_ID";
var oTable = sap.ui.getCore().byId("tblProviders");
oModel.read(Context, null, null, true, onSuccess, onError);
function onSuccess(oEventdata){
    var outputJson = {};
    var p = 0;
    var r = {};
    try {
        if (oEventdata.results){
            r = oEventdata.results;
    } catch(e){
        //alert('oEventdata.results failed');
    $.each(r, function(i, j) {
        outputJson[p] = {};
        outputJson[p]["NAME"] = j.NAME;
        outputJson[p]["ID"] = j.ID;
        outputJson[p]["PARENT_ID"] = j.ID;
        outputJson[p]["DELETE"] = 0;
        var m = 0;
        if (j.ASSIGNEDCHILD.results.length > 0) {
            $.each(j.ASSIGNEDCHILD.results, function(a,b) {
            outputJson[p][m] = { NAME: b.NAME,
                                 ID : b.ID,
                                 PARENT_ID: b.PARENT_ID,
                                 DELETE: 1};
            m++;
        p++;
    var oPM = new sap.ui.model.json.JSONModel();
    oPM.setData(outputJson);
    oTable.setModel(oPM);
function onError(oEvent){
    console.log("Error on Provider Members");
oTable.bindRows({
    path:"/"
