[BUG] `Bad Request: chat not found` for groups with 10 digits ID

[Jagerente]

Information

I am using func (*tgbotapi.BotAPI).Send(c tgbotapi.Chattable) (tgbotapi.Message, error) to send messages to multiple groups. When i'm attempting to send a message to some groups i'm receiving Bad Request: chat not found error.

• Bot added to all groups i'm working with.
• I have verified group IDs multiple times.

Some researching

• Issue is consistently observed across a total of 157 chats. Chat IDs ranges from -3******** (9 digits) to -1********* (10 digits).
• Error occurs ONLY for chats within 10 digits IDs (with 1 exception of 19 tested).

Im having the same issue. tried with - and without. Is this a bug?

    msg := tgbotapi.NewMessage(int64(...), "test")

    res, err := bot.Send(msg)
