downloadFile, addFileToDownloads, Priority fails

[TunifyBasic]

sorry if i'm being annoing but i don't know here is what's going on:

def message_video(chat, chat_id, msg_id, content):
    vid_obj = content.get("video")    # in shea Allah: download thumbnails and this stuff...
    video = vid_obj.get("video")
    caption = vid_obj.get("caption")
    remote = video.get("remote")
    id = remote.get("id")
    print(chat_id, msg_id, id)
    td_send({ '@type': 'addFileToDownloads', 'file_id_': id, 'chat_id_': chat_id, 'message_id_': msg_id, 'priority_': 31 })

errors:

-10015579179xx 2765472399xx BAACAgQAAx0CaNRkgQABBAY4Z2I9IMlBSo9nDbTzGaPJp1y7QCcAAiEYAAJpMBBTfOp20nGOv1w2XX
{'@type': 'error', 'code': 400, 'message': 'Priority must be between 1 and 32', '@client_id': 1}

i changed the file priority to 1 -1 16 32 31 33 but it always say priority must be between 1 and 32 also done it using downloadFile and still same issue.

The parameters of requests never ends on underscores in JSON interface. Underscores are added to field names only in C++ interface, documentation for which is available at https://core.telegram.org/tdlib/docs/. The correct name of the parameter is "priority".
