Hi. Please double check that your bot is a member of that chat. Note that bots can only be members of a channel if they are admin in that channel. To double check thechat_id, you can also extract it from the updates that your bot gets from that chat.

Hi, you need to add "-" as prefix for your chat id, for example if chat id is 12345, you need to add -12345

@Bibo-Joshi
My bot is gettingtelegram.error.BadRequest: User not found in a group when usedbot.getChatMember.
It has the right of sending messages in the chat.

1. It doesn't happen once in the blue moon. It is consistent.
2. It happens for all the users, I tried it out manually.
3. In other groups, it works fine. ( even when with just sending message right )
4. The group is a public supergroup

Please don't Tag people just to get attention.

You are one of the participants in this issue. That's the reason of me mentioning you.

After installedpython-telegram-bot, I ran a simple script as bellow:

from telegram import Botmy_token = '534*******:AAF*************'channel_id = -10016********def push_message(msg, chat_id=channel_id) -> None:    bot = Bot(my_token)    bot.sendMessage(chat_id, msg)push_message('Hello channel')

I got an errortelegram.error.BadRequest: Chat not found Someone please help me. I checked the channel ID and I think it's correct. I copied the message link from the channel then got the channel ID from this URL.

I got the same issue too and didn't know how to resolve it.

I resolved the issue. I found the previous channel id was incorrect. I issued the following command:

https://api.telegram.org/bot<TOKEN>/getUpdates

and check the id is -1002XXXXXXX under the channel name
