angular not displaying object inside array of object

Question

i'm using angular to get data from an api.. the data structure i have is array(object).array(object)

this is my data

and this is the component ts

export class LoginComponent implements OnInit {

collaborator:Collaborator[]=[];
entreprise:Entreprise[]=[];


  constructor(private serv:EntrepriseService) { }

 getcoll(){
  this.serv.getcollaboratorses().subscribe(res =>{
     this.collaborator = res.content;
     // this.entreprise=res.content.entreprise;
      console.log(res);
    },err =>{

      console.log(err);
    });
}

the collaborator module

import {Entreprise} from './entreprise';
export interface Collaborator {

    id:String;
    name:String;
    email:String;
    password:String;
    phone:String;
    entreprise:Entreprise[];
    roles:any[];
}

entreprise module

export interface Entreprise {

    id:String;
    name:String;
    socialPurpose: String;
    businessCode:String;
    activityDomain:String;
    email:String;
    password:String;
    logo:String;
    roles:any[];

ee.entreprise is an array, name doesn't exists there. warp it with another ngfor like in the code below

<p *ngFor="let colab of collaborator">
   {{colab.name}} - 
    <ng-container *ngIf="colab.entreprise?.length"> 
        <span *ngFor="let ee of colab.entreprise"> 
            {{ee.name}} 
        </span>
    </ng-container>
  </p>

The ee.enterprise is an array, the ee.enterprise.name does not exist. First it has to be indexed. For example "ee.enterprise[0].name, ee.enterprise[1].name and so on.

Most probably an other ngFor will be needed for the array of ee.enterprise.
