Unable to join private channel using telegram's new invite hash format.

[dsx12]

It is no longer possible to join a private channel via their invite links/hashes. I will provide a proof of concept of the failure and the corresponding error log below.

import asyncio
from telethon.sync import TelegramClient
from telethon.tl.functions.messages import ImportChatInviteRequest

async def main():
    tg_hash = '<enter_invite_hash_here>'
    async with TelegramClient('anon', <enter_API_id_here>, '<enter_API_hash_here>') as client:
        chat_invite = await client(ImportChatInviteRequest(tg_hash))
asyncio.run(main())

File "test.py", line 27, in main
    chat_invite = await client(ImportChatInviteRequest(tg_hash))
  File "/home/test/.local/lib/python3.7/site-packages/telethon/client/users.py", line 30, in __call__
    return await self._call(self._sender, request, ordered=ordered)
  File "/home/test/.local/lib/python3.7/site-packages/telethon/client/users.py", line 79, in _call
    result = await future
telethon.errors.rpcerrorlist.InviteHashExpiredError: The chat the user tried to join has expired and is not valid anymore (caused by ImportChatInviteRequest)

Raises InviteHashExpiredError even when:

• After stripping/remove '+' character from the telegram invite hash string (example: hlQ3QhNi6q05ZDIx).
• Providing full telegram invite hash string (example: +hlQ3QhNi6q05ZDIx
• Providing full telegram invite hash string with link/t.me domain (example: https://t.me/+hlQ3QhNi6q05ZDIx)

Have you installed the development version to test this? Please use the issue templates. They exist for a reason.

[dsx12]

I've tested it with my own API hash and API ID.

[Lonami]

API ID and hash to not affect how the API behaves (to my knowledge). The layer used (which is the latest in the development version) does though.

I have same problem , did you solved it ?

Same issue

Hi. I have faced the same issue. Here is a solution:

1. Use hash without "+" character, like in your first example.
2. Call the API like above: await client(ImportChatInviteRequest(hash=tg_hash))

Thanks , and how can we get entity of the group?

[Mariownyou]

assign the result to this await channel = await client(ImportChatInviteRequest(hash=tg_hash))

I use await client(ImportChatInviteRequest(hash='hlQ3QhNi6q05ZDIx')) but it can't work

[arthurbarros]

Any ideias how to make this work? Not able to join a private channel with the invite links that have a + sign, strip it or not

[DLX23]

i got the same Problem. Any Ideas to fix it?

[0xdefidevin]

I also am getting this problem

[lorrod]

I think the main reason caused links which are required admin approval to join.

I have tested regular links - it is working Admin approval links are not working

[parotikov]

Same problem. Does anybody solved it?

[DLX23]

yes, i solved it. i changed https://t.me/+ab12xxxxxxx to https://t.me/joinchat/ab12xxxxxx

[parotikov]

yes, i solved it. i changed https://t.me/+ab12xxxxxxx to https://t.me/joinchat/ab12xxxxxx

But problem in hash ab12xxxxxx, without +, /joinchat/ or anything else in url. ImportChatInviteRequest(hash='hlQ3QhNi6q05ZDIx')) doesn't accept hash, it return an error.

Anyway, somebody says, that I can use newthon. It solve the problem.

[DLX23]

i use client.get_entity(chan_url) did you use excatly the same format? https://t.me? if /joinchat/ isn present, add it... i try it in browser first. build the correct url.

[Lonami]

Closing since v1.25 available in PyPi should accept the new invite link hash.
