APEX

I'm using this code but getting no file on the browser.
The log even says Starting Download of "repot.csv"

DECLARE
    l_export       apex_data_export.t_export;
    l_region_id    number;
BEGIN

   SELECT region_id into l_region_id
     FROM apex_application_page_regions
    WHERE application_id = 100
      and page_id = 3
      and static_id = 'classic_report';
    
    l_export := apex_region.export_data (
         p_format       => apex_data_export.c_format_html,
         p_page_id      => 3,
         p_region_id    => l_region_id );
         
    apex_data_export.download( l_export );
END;
