Bug Report

I run into a problem when I attempt to prerender a dynamic page that uses the returned data from a service using a JSON file.

It seems it does not wait until the second round of callbacks / async actions are done and rerenders a version without the data that is returned from the service.

in constructor...

this._articlesService.getArticleData(this.articleID).subscribe(
            (data) => {
                this.articleSettings = data;
                //console.log(data);
                this.articlesInitOnStart();
            },
            (err) => {
                console.log(err);
            }
        );


in ArticlesService....

getArticleData(articleID: number): Observable<any> {

        return this.httpClient.get<any>("./assets/data/articles/" + articleID + ".json")
            .pipe(catchError(this.handleError));
    }
