The problem when adding to a telegram chat using Telethon

I am new to python. I am trying to use the telethon shell to add and remove users from a chat. I use the example code taken from here https://tl.telethon.dev/methods/messages/add_chat_user.html

My code:

(ID and hash I replaced in the text with arbitrary numbers)

from telethon.sync import TelegramClient
from telethon import functions, types
from telethon.errors import ChatIdInvalidError
from telethon.errors import PeerIdInvalidError
from telethon.errors import UserNotParticipantError
from telethon.tl.functions.messages import DeleteChatUserRequest
from telethon.tl.functions.messages import AddChatUserRequest


api_id = 1234567
api_hash = 'blablablabla123456'
phone = '+123456789'
name = 'testname'

with TelegramClient(name, api_id, api_hash) as client:
    result = client(functions.messages.AddChatUserRequest(
        chat_id=12345678912,
        user_id='username',
        fwd_limit=42
    ))
    print(result.stringify())

But unfortunately for me it doesn't work and gives an error.

(ID and hash I replaced in the text with arbitrary numbers.)

    Request caused struct.error: argument out of range: AddChatUserRequest(chat_id=123456789, user_id=InputUser(user_id=123456789, access_hash=-123456789789), fwd_limit=42)
Traceback (most recent call last):

    return self._bytes()

    struct.pack('<i', self.chat_id),
struct.error: argument out of range

Telethon ver. 1.22.0

I would be grateful for any help

Thank you!

The "argument out of range" error I which indicated in the question, occurred because I was trying to specify a 40 byte Chat_id. Whereas for regular chats, the maximum id is 32 bytes.

This happened as you need to specify the so-called "real" id. As an example, the id that Telegram bots receive looks something like this -1001234567891 the real id would be 1234567891.

You can use the following code to get the real id:

from telethon import utils
real_id, peer_type = utils.resolve_id(-1001234567891)

print(real_id)  # 1234567891
print(peer_type)  # <class 'telethon.tl.types.PeerChannel'>

peer = peer_type(real_id)
print(peer)  # PeerChannel(channel_id=1234567891)

However, if you specify a real id, a ChatIdInvalidError may appear. The problem is that the AddChatUserRequest method can only be used with regular "chats" In my case, it was "supergroup" - is a Channel with the channel.megagroup attribute set to True

For them need use InviteToChannelRequest method, the code that worked was like this:

from telethon.sync import TelegramClient
from telethon import functions, types
    
api_id = 123456
api_hash = '******'
name = 'name'
    
with TelegramClient(name, api_id, api_hash) as client:
    result = client(functions.channels.InviteToChannelRequest(
            channel='channelname',
            users = ['username']
        ))
    print(result.stringify())

Then I created a regular "chat" group

For her, the working code was like this:

from telethon.sync import TelegramClient
from telethon import functions, types
    
api_id = 123456
api_hash = '*******'
name = 'name'
      
with TelegramClient(name, api_id, api_hash) as client:
   result = client(functions.messages.AddChatUserRequest(
        chat_id=chatid,
        user_id='username',
        fwd_limit=42
    ))
    print(result.stringify())

Use:

result = await client(functions.messages.AddChatUserRequest(
        chat_id=12345678912,
        user_id='username',
        fwd_limit=42
    ))

Instead of:

result =  client(functions.messages.AddChatUserRequest(
        chat_id=12345678912,
        user_id='username',
        fwd_limit=42
    ))
