How to get reactions to messages?

[autoantwort]

I want to get reactions to my messages and use the following code:

const TelegramBot = require('node-telegram-bot-api');
const TOKEN = '***';

const bot = new TelegramBot(TOKEN, {
    polling: {
        params: {
            allowed_updates: ["message", "message_reaction"],
        }
    }
});

console.log(TelegramBot.messageTypes)

bot.on('message', (msg) => {
    bot.sendMessage(msg.chat.id, 'Try reacting to this message!');
});

bot.on('message_reaction', (reaction) => {
    console.log('Reaction received (message_reaction):', reaction);
});
bot.on("message_reaction_count", async (reaction) => {
    console.log("message_reaction_count", reaction);
});
console.log('Bot started with polling enabled');

But when i send the bot a message and react to it I don't get a update. Do you have a idea what the problem could be?

I don't know for some reason node-telegram-bot-api can not handle this properly.

Just hit this link from your browser (only once), and after that you will get updates on message reactions
https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates?allowed_updates=["update_id","message","edited_message","channel_post","edited_channel_post","inline_query","chosen_inline_result","callback_query","shipping_query","pre_checkout_query","poll","poll_answer","my_chat_member","chat_member"]

I don't know for some reason node-telegram-bot-api can not handle this properly.

Just hit this link from your browser (only once), and after that you will get updates on message reactions https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates?allowed_updates=["update_id","message","edited_message","channel_post","edited_channel_post","inline_query","chosen_inline_result","callback_query","shipping_query","pre_checkout_query","poll","poll_answer","my_chat_member","chat_member"]

The way this works is because this link actually hits with the correct parameters, particularly for the allowed_updates. Currently, node-telegram-bot-api doesn't handle if we put it as an array.

You can test it if we hit that link, then modify the allowed_updates to ["message_reaction"].
The bot should not receive message updates, but it will receive them anyway because the previous setting (from the link) will be used as stated in the documentation.

Specify an empty list to receive all update types except chat_member, message_reaction, and message_reaction_count (default).
If not specified, the previous setting will be used.

It explains why the bot never gets message_reaction.

TLDR:

• TelegramBot never passed the defined allowed_updates if we defined it as an array.
• node-telegram-bot-api doesn't handle the allowed_updates on Telegram bot polling if the value is an array.
• message_reaction will never be received because it's excepted by default.

So, we need to JSON.stringify the array like this:

const bot = new TelegramBot(TOKEN, {
    polling: {
        params: {
            allowed_updates: JSON.stringify(["message", "message_reaction"]),
        }
    }
});

I think we should put it as an array by default.
I've created a PR for this, so we can handle it if the developer puts an array on it.

#1270

This is the result on my local. I make the bot send a message whenever there is a reaction on its message.
