please post your model

[mysteriousgirl7]

this is album model

import { Resource } from 'hal-4-angular';
import { Artist } from './artist.model';
export class Album extends Resource {
id: number;
title: string;
artist: Artist[];
stockLevel: number;
links: any[];

}

this is artist model

import { Resource } from 'hal-4-angular';

export class Artist extends Resource {
id: string;
name: string;
}

this is component

export class ActiveRepairOrderComponent implements OnInit {
albums: Album[];
//album: Album;

constructor(private albumService: AlbumService) { }
ngOnInit() {
this.getAllAlbums();

}
getAllAlbums() {
this.albumService.getAll().subscribe((albums: Album[]) => {
// when we hit the subscribe function there is an error can't convert null to object

this.albums = albums;

});

}
}

////this is service
export class AlbumService extends RestService {

constructor(injector: Injector) {

super(Album, 'albums', injector);  

}

Are you sure you are using Spring Data Rest with HAL?
