ngx-translate does not seem to work with AOT

[123city]

Current behavior

We use NGX-translate as follows:

import {TranslateModule, TranslateLoader} from '@ngx-translate/core';
import {TranslateHttpLoader} from '@ngx-translate/http-loader';

export function httpLoaderFactory(http: HttpClient) {
    return new TranslateHttpLoader(http, "assets/i18n/", ".json");
}

TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useFactory: httpLoaderFactory,
                deps: [HttpClient]
            }
})

When executing npm build --prod we get the following errors:

ERROR in ./src/app/app.module.ngfactory.js
Module not found: Error: Can't resolve '@ngx-translate/core/index' in 'C:\Projects\process-mgt\src\app'

When we run npm build --prod --aot=false --buildOptimizer=false we don't get this error.

Expected behavior

How do you think that we should fix this?

Same problem here. With Ivy, AOT mode is recommended, so this issue will become more important in the upcoming future.
