TypeError: writeInt64(self, i: int): argument 1 has unexpected type 'NoneType'

[MIHUTKA3]

Describe the bug
I took the code from the example to create the tdata folder and created a session through the telethon library

Code

Next, I specified this session in this code

Code

A tdata folder is created, and another one is stored in it, where only maps are stored. That's not enough for a full tdata

Expected behavior
I wanted to see the tdata in the created folder
