Jak se dostat pole dat k vykreslení v html templete v Úhlové ngOnInit

Snažím se načíst informace z backendu a ukazuje, že v Úhlové komponenty. Ale já jsem pro něj v ngOnInit první před vykreslování, ale ukazuje se mi chyba v úhlové. Je to moje součást.ts souboru

import { Component, OnInit } from '@angular/core';
import { UserService } from '../shared/user.service';
import { Router } from '@angular/router';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {

  constructor( private userService: UserService, private router: Router) { }

  userDetails = [];

  ngOnInit(): void {
    this.userService.getUserProfile().subscribe(
      (res:any)=>{
        this.userDetails = res['user'];
      },
      err=>{}
    );
  }

  onLogout(){
    this.userService.deleteToken();
    this.router.navigate(['/login']);
  }

}

To je moje component.html soubor

<table #ngIf="userDetails" class="table-fill">
    <thead>
        <tr>
            <th colspan="2" class="text-center">
                User Profile
            </th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>First Name</td>
            <td>{{userDetails.name}}</td>
        </tr>
        <tr>
            <td>Email</td>
            <td>{{userDetails.email}}</td>
        </tr>
        <tr>
            <td colspan="2" class="text-center">
                <input type="button" (click)="onLogout()" value="Logout">
            </td>
        </tr>
    </tbody>
</table>

To je chyba, jsem stále
