Use Juicebox on dashboard

Hi everyone, I’m trying to create a dashboard widget displaying a Juicebox gallery but it doesn’t load the gallery…

function galeria_dashboard_widget_function() { // gallery widget
	$current_user = wp_get_current_user();
	echo do_shortcode('[juicebox gallery_id="'. $current_user->ID .'"]');
}
function galeria_add_dashboard_widgets() {
	wp_add_dashboard_widget('galeria_dashboard_widget', 'Galeria', 'galeria_dashboard_widget_function');
}
add_action('wp_dashboard_setup', 'galeria_add_dashboard_widgets' );

Thanks in advance!
