switching from .session to tdata not working

[vnpresent]

I tried it, although it creates a folder tdata but there is no login on it

It's still working for the latest version of Telegram Desktop. Can you post your code here and also specify which version of Telegram Desktop you're using?

Edit: Please make sure that you have the latest version of opentele

pip install -U --no-cache-dir opentele

I run the code from the example and raises an error...

from opentele.td import TDesktop
from opentele.tl import TelegramClient
from opentele.api import API, UseCurrentSession
import asyncio
import os

async def main():
    client = TelegramClient('62895385923488.session')
    tdesk = await client.ToTDesktop(flag=UseCurrentSession)   # error occurs here
    tdesk.SaveTData()#"tdata")

asyncio.run(main())

-----------------------------------------------
File "/home/af/.local/lib/python3.9/site-packages/opentele/td/account.py", line 1007, in FromTelethon
    Expects(
opentele.exception.TelethonUnauthorized: TelethonUnauthorized: Telethon client is unauthorized, it need to be authorized first [ Called by FromTelethon() ]

how to make it work?

The error is:

TelethonUnauthorized: Telethon client is unauthorized, it need to be authorized first

Your .session file is not authorized yet, that mean you haven't logged in.

Everything miraculously worked after your answer. Thanks! But now I don't understand why it didn't work...

This is your code from account.py :

..........
else:
            copy = telethonClient

ss = copy.session
authKey = ss.auth_key.key
dcId = DcId(ss.dc_id)
userId = copy.UserId
authKey = td.AuthKey(authKey, td.AuthKeyType.ReadFromFile, dcId)

if userId == None:
    await copy.connect()
    await copy.get_me()
    userId = copy.UserId  # the problem was here
..........

copy.UserId was returning None. I do not understand why I did not connect with the client? Now everything connects and gets the userId. I am now going to use your library. Suddenly I have questions, let me disturb you in telegrams? For efficiency ... My telegram @AlexFX77

I'm sorry for my English, I'm using google translate...
