USER_BANNED_IN_CHANNEL

USER_BANNED_IN_CHANNEL.md

Description

Can't understand the meaning of returned exception USER_BANNED_IN_CHANNEL on sending chatAction to the supergroup while @TrueMafiaBot (id: 468253535) is a member of that supergroup (e.g. -1001639443192) and has all required permissions.

Looks like a #bug. I know about 3000 groups with similar bot behaviour.

Workaroud

I tell my users to give admin permissions to the bot - it helps to avoid described behaviour.

How to reproduce

All described below JSONs are not modified, just masked token in URLs and chat join link.

Chat action

Let's try to send chat action...

Request

https://api.telegram.org/bot{{token}}/sendChatAction

{
    "action": "typing",
    "chat_id": -1001639443192
}

Response

{
    "ok": false,
    "error_code": 400,
    "description": "Bad Request: USER_BANNED_IN_CHANNEL"
}

ChatMember

May be bot is really banned? Let's look...

Request:

https://api.telegram.org/bot{{token}}/getChatMember

{
    "chat_id": -1001639443192,
    "user_id": 468253535
}

Result:

{
    "ok": true,
    "result": {
        "user": {
            "id": 468253535,
            "is_bot": true,
            "first_name": "True Mafia",
            "username": "TrueMafiaBot"
        },
        "status": "member"
    }
}

Chat

May be Chat has restricted permissions by default?
May be Chat has a wrong type (e.g. channel)?
Let's check...
