Error: parsing json file angular 5

[andrei-ga]

I just updated to Angular 5. I am using asp-prerendering from .Net Core 2 feature.
I import the plugin using

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

and

export function createTranslateLoader(http: HttpClient, baseHref: string) {
    // Temporary Azure hack
    if (baseHref === null && typeof window !== 'undefined') {
        baseHref = window.location.origin;
    }
    // i18n files are in `wwwroot/assets/`
    return new TranslateHttpLoader(http, `${baseHref}/assets/i18n/`, '.json');
}

I am receiving the following error: NodeInvocationException: Http failure during parsing for http://localhost:50475/assets/i18n/en.json

If I disable pre-rendering or I don't import ngx-translate plugin, everything works.

I've faced the same bug.

Check for a trailing , or attributes not wrapped in quotes... the http.get method is pretty picky about proper JSON syntax. I had the same issue until I (finally) found the one lone trailing comma that was causing this non-descript error. HTH!

Try using a tool to validate your JSON - that was my issue, super picky formatting; no trailing commas, wrap all attribute names in quotes, etc. Try this: https://jsonlint.com/

It is valid. I checked with several tools, including the one you provided.

I have checked already, but there's not a typing error.
will some one guide me?
