     print(filepath)
     return send_file(filepath, as_attachment=True, attachment_filename='Controle_Fiches_Appui.xlsx')
  except Exception as e:
     return str(e)

the filepath is good but when i try to download it from postman or a python client the return file is blank with 0 octect .. please help me

You should use send_from_directory rather.

send_file is just creating an empty file and giving it to you, also if its a GET request it will be cached and you will get the same file repetitively.

Why not try downloading in incognito mode to test
