angular - Kunne ikke laste inn ressurs: serveren svarte med status 404 (Ikke funnet) - iOS-enhet Ionic 3

Det viser denne feilen:

Kunne ikke laste ressurs: serveren svarte med status 404 (Ikke funnet)

Jeg har brukt denne CLI-en og testet på iOS-enhet versjon 12.1.1:

ionic cordova run ios --prod --device

Merk: Dette fungerer fint på en Android-enhet. Noen anelse?

.html

 <ion-slide *ngFor='let page of pages | normalizeUri'>
      <img [src]='page.documentPreviewImageFileUri' />
   </ion-slide>

pipe.ts

@Pipe({
  name: 'normalizeUri',
  pure: false
})
export class NormalizeUriPipe implements PipeTransform {

  constructor(private imageHandlingProvider: ImageHandlingProvider) { }
  transform(pages: Page[]): string[] {
    return pages.map((p) => {
      return this.imageHandlingProvider.normalizeImageFileUri(p.documentPreviewImageFileUri || p.originalPreviewImageFileUri);
    });
  }

}

provider.ts

import { normalizeURL } from 'ionic-angular';

@Injectable()
export class ImageHandlingProvider {

  constructor() {
  }

  normalizeImageFileUri(imageFileUri: string): string {
    console.log('imageFileUri', imageFileUri);
    console.log('imageFileUri-normalizeURL', normalizeURL(imageFileUri));
    return normalizeURL(imageFileUri);
  }

Noe konsollutdata:

 [Log] imageFileUri - "file:///var/mobile/Containers/Data/Application/C7C43E62-A782-4CA1-97A6-
    AE19B319EA16/Library/Application%20Support/net.doo.ScanbotSDK/SBSDK_I…" 
    (cordova.js, line 1732) 

    [Warning] normalizeURL is deprecated, use

Plugin :

<plugin name="cordova-plugin-ionic-webview" spec="1.2.1" />
