this.masonry is undefined

[dmcgrandle]

getting an error attempting to use this module. Apparently the provider injection is not working.

Here is a snip from photo.module.ts:

import { Masonry, MasonryModule } from '@thisissoon/angular-masonry';
import { SharedModule } from '../shared/shared.module';
import { PhotoRoutingModule } from './photo-routing.module'; 
import { AlbumsComponent } from './albums/albums.component';
import { PhotosComponent } from './photos/photos.component';

const masonryProviders = [
    { provide: Masonry, useFactory: () => window['Masonry'] }
];

@NgModule({
    imports: [
        CommonModule,
        PhotoRoutingModule,
        SharedModule,
        MasonryModule.forRoot(masonryProviders),
    ],

Here is the error in the browser on use:

ERROR TypeError: _this.masonry is not a constructor

Here is a console.log('masonry is:', masonry) from inside the component:

masonry: undefined

Thanks for any help.
