    intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        // add authorization header with jwt token if available
        let currentUser = this.authenticationService.currentUserValue;
        if (currentUser && currentUser.access_token) {
            request = request.clone({
                setHeaders: {
                    Authorization: `Bearer ${currentUser.access_token}`,
                    //'Access-Control-Allow-Origin': '*'
                }
            });
