I work on a web application with ASP.NET Core 6 and Angular 13.

This application displays a list of items successfully without any issue. My issue happens when there's pagination for the items displayed.

I get an error in the console:

ERROR Error: Cannot find a differ supporting object '[object Object]' of type 'object'. NgFor only supports binding to Iterables such as Arrays.

What I have tried:

What I tried is:

(1) Create Web API action to display all items

public async Task<IActionResult> GetAll(int pageNumber = 1)
    var allitems = _iitem.GetAllItems();

    var result = _pageHelper.GetPage(allitems.AsQueryable(), pageNumber);

    var itemsdata = new ItemsPageViewModel
                items = result.Items,
                Pager = result.Pager

    return Ok(itemsdata);
When I call this action method, it returns json data as shown here:

    "items": [
            "id": 3,
            "itemNameER": "قلم",
            "itemNameEN": "pen",
            "description": "1"
            "id": 4,
            "itemNameER": "قلم",
            "itemNameEN": "pencil",
            "description": null
            "id": 5,
            "itemNameER": "قلم",
            "itemNameEN": "pen2",
            "description": null
    "pager": {
        "numberOfPages": 1,
        "currentPage": 1,
        "totalRecords": 3
(2) In Angular 13, I created a service in service.ts:

export class ErpServiceService {

  constructor( private http: HttpClient ) { }

  getAll(): Observable<any> {
    return this.http.get(baseUrl);
(3) I created a component items logic in component.ts:

ngOnInit(): void {
  retrieveAllItems(): void {
        data => {
          this.items = data;
        error => {
(4) I created a component view component.html:

<table id="customers">
  <tr *ngFor="let item of items">
How to apply pagination on item rows displayed?
