Chat not found

[N3R00]

I'm trying to send messages to a channel I have, but it just gives me an error that the chat was not found

let chat = await bot.getChat(-1611586710) bot.sendMessage(chat, 'Hello World!');

Is the bot in the channel with any privileges?

If not, put the bot in the channel and send a random message. Now try sending the message as you were doing before.

const chatId = -1611586710; 
bot.sendMessage(chatId, 'HelloWorld');
