Bug de Binding das Propriedades de Photo (url e description) no Template de PhotoList

Ao tentar executar o ng serve -o, estou recebendo esse erro de compilação abaixo:

Error: src/app/photos/photo-list/photo-list.component.html:5:2 - error NG8002: Can't bind to 'url' since it isn't a known property of 'app-photo-list'.   

5  [url]="photo.url"
   ~~~~~~~~~~~~~~~~~

  src/app/photos/photo-list/photo-list.component.ts:7:16
    7   templateUrl: './photo-list.component.html',
                     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Error occurs in the template of component PhotoListComponent.

Abaixo está o código do PhotoListComponent

import { Component, OnInit }    from '@angular/core';
import { Photo }                from '../photo/photo';
import { PhotoService }            from '../photo/photo.service';

@Component({
  selector: 'app-photo-list',
  templateUrl: './photo-list.component.html',
  styleUrls: ['./photo-list.component.css']
})
export class PhotoListComponent implements OnInit {
                                // avoid any runtime error if ngOnInit() is not defined correctly
  photos: Photo[] = [];

    // Using the Constructor only for Dependence Injections
    constructor(private service: PhotoService) {
    }

    // Any setup needed its going to be done here
    // Phase On Init occurs after Instacialization and after this component receive the Inbound properties.
    ngOnInit(): void {
        this.service.listFromUser('flavio')
            .subscribe(
                // Observable is a Lazy object. It will not access the URL unless there is an Observer.
                photos => {
                    console.log(photos);
                    console.log(photos[0].description);
                    this.photos = photos;
                }
            );
    }

}

Abaixo está o código do PhotoList Template:

<p>photo-list works!</p>

<app-photo-list 
    *ngFor="let photo of photos"
    [url]="photo.url"
>
</app-photo-list>

Abaixo está o PhotoModule, já contendo o Import para o CommonModule:

import { NgModule }                from '@angular/core';
import { CommonModule }            from '@angular/common';
import { HttpClientModule }        from '@angular/common/http';

import { PhotoComponent }        from './photo/photo.component';
import { PhotoListComponent }    from './photo-list/photo-list.component';

@NgModule({
    declarations: [
        PhotoComponent, 
        PhotoListComponent
    ],
    exports: [PhotoComponent],
    imports: [
        HttpClientModule,
        CommonModule
    ]
})
export class PhotosModule {

}

Tentei as soluções mais óbvias, como alterar o Tipo do atributo do PhotoListComponent de Photo[] para any[], sem sucesso.

Onde estou errando e como corrigo esse bug?
