Can't forward messages to anyone but myself

[IvanMazzoli]

I'm trying to forward a message to a group but it doesn't allow me to do it. The only chat I'm able to forward messages is my own chat (saved messages).

What I've tried: client.forward_messages(-100129xxxxxxx, chat_id, msg_ids) to a group, doesn't work. client.forward_messages(446xxx, chat_id, msg_ids) to my friend, doesn't work. client.forward_messages("@myfriendusername", chat_id, msg_ids) to my friend, doesn't work. Same without the @.

The log file shows this error (it's similare between al cases, changes only the KeyError):

Also, I'm an administrator in the destination group, my friend hasn't blocked me and the key/access_hash is correct. I'm using Pyrogram V.0.3.3

@IvanMazzoli About client.forward_messages(-100129xxxxxxx, chat_id, msg_ids): -100129xxxxxxx is the ID the Bot API is using when referring to channels/supergroups, but in Pyrogram (at the moment) you must remove the -100, so your channel/supergroup IDs should look like: 129xxxxxxx.

Regarding the other two (but probably applies to the first one too): Does chat_id contain the ID of an entity (user/group/channel) you have already contacted/joined before? You won't be able (for now) to forward messages from/to entities you don't have in your dialogs list.

[IvanMazzoli]

Thanks @delivrance, removing -100 did the job! For the other two, chat_id contains in the first case the chat ID of the user (obtained from a "normal" bot, could be it the cause of the problem?), in the second case the public ID of my friend. I have indeed already talked to this person, I also have his phone number.

[delivrance]

Users IDs taken from bots are fine, as soon as you have a conversation with them in your dialogs list. Can you post the full traceback of both calls separately?

[IvanMazzoli]

Sure, but now to be sure I've talked with my own other Telegram account and replaced chat_id and public ID. If you see different variables in my code, don't worry because it works by forwarding to a supergroup ;)

• Trying with chat_id:

Please post your code, I'll try to replicate this issue tomorrow.

[IvanMazzoli]

The basic idea of the script is to forward messages from channels to a specific group, here's the full source code.

import logging
from pyrogram import Client
from pyrogram.api import types

def callback(update):
    if isinstance(update, types.Update):
        for upd in update.updates:
            if isinstance(upd, types.UpdateNewChannelMessage) and upd.message.post:
                print('>> New channel message!')
                logging.basicConfig(filename='log.txt',level=logging.DEBUG)
                ids = [upd.message.id]
                client.forward_messages("@myfriendusername", upd.message.to_id.channel_id, ids)
                logging.info('###################################')
                logging.info(str(upd))

client = Client(session_name="tdi")
client.set_update_handler(callback)

client.start()
client.idle()

I've pushed a change that might fix this. Try again your code after you upgrade using pip install --upgrade git+https://github.com/pyrogram/pyrogram

You can also do this manually as explained here: https://docs.pyrogram.ml/getting_started/QuickInstallation/#bleeding-edge

[IvanMazzoli]

Okay, now using @username works as intended. Unforunately, using a chat_id like 2977xxxx doesn't work.

This means you don't have 2977xxxx in your dialogs list (i.e., you have not a conversation with him, yet), do you?

[IvanMazzoli]

I thought too this was the error, but this is what I did: • With my "normal" account, got the chat_id from one of my bots (I'm sure it's right, I use the same chat_id value for operations in MySQL without problems); • Still with the "normal" account, talked to my MTProto account; • Switched to my MTProto account, talked to my "normal" account; • Trying to forward messages to my "normal" account. If I forward to it with the @username it works fine, the problem is if I try to use the 2977xxxx identifier

[IvanMazzoli]

We figured it out, now I was passing the ID as a String instead of an Int
