Angular6 - ng build / serve --prod - Error during template compile of 'AppModule'

I have this problem when I’m building or seving an Angular6 application for PROD with ng serve --prod or ng build --prod

ERROR in app/app.module.ts(84,47): Error during template compile of 'AppModule'
  Complex function calls are not supported. in 'intersectionObserverPreset'
    'intersectionObserverPreset' references 'intersectionObserverPreset'
      'intersectionObserverPreset' references 'intersectionObserverPreset'
        'intersectionObserverPreset' contains the error.

This is what I have in the line app/app.module.ts(84,47)

import { LazyLoadImageModule, intersectionObserverPreset } from 'ng-lazyload-image';
@NgModule({
    imports: [
             ...,
/*84 -->*/ LazyLoadImageModule.forRoot({ preset: intersectionObserverPreset }) /*<-- 84*/
    ],
    declarations:  [...],
    entryComponents [...],
    providers: [...],
    bootstrap: [...]
})

Versions:

angular: 6.1.0
ng-lazyload-image: 5.0.0
npm: 5.6.0
node: 8.11.4
typescript: 2.7.2

It seems to have something to do with AOT but I can’t find a way to fix it. This error does not occur when normally running the commands ng build or ng serve

I appreciate any help

Thanks!

I have the exactly same issue, and I am using angular version 7. It wokrs on ‘ng serve’ but not ‘ng build --prod --aot’

is there any solution for the issue?

Updating to ng-lazyload-image@5.1.2 and angular 7 solved the issue. Thanks for resolving .
