Converting session into tdata problem

[floutehh]

my code here

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

async def main():

# Load the client from telethon.session file
# We don't need to specify api, api_id or api_hash, it will use TelegramDesktop API by default.
client = TelegramClient("xxxxxxxxx.session")

# flag=UseCurrentSession
#
# Convert Telethon to TDesktop using the current session.
tdesk = await client.ToTDesktop(flag=UseCurrentSession)

# Save the session to a folder named "tdata"
tdesk.SaveTData()#"tdata")

asyncio.run(main())

When i run the whole code, i got error
