Not getting an update with callback_query when user presses an inline button (Telegram webhook)

Using node-telegram-bot-api. I have a Webhook that works properly – i get updates when messages are sent, but no update is sent when the user presses a button in an inline keyboard.

class BotController {
    async handleUpdate(req, res, next){
        console.log(req.body);

        if (req.body.message.text === "/getTypes"){
            sendTypesKeyboard(req.body.message.chat.id);
        }
        return res.json({message: "update handled"});
    }    
}

const sendTypesKeyboard = async (chatId) => {
    const types = await typeDbHandler.getAll();
    const options = {
        reply_markup: JSON.stringify({
            inline_keyboard: types.map((type) => 
                [{"text": type.name, "callback_data": type.id}]
            )
        })
    }
    bot.sendMessage(chatId, "Choose the type", options);
}

I tried to use polling and handle a callback_query event, but it didn’t work either

const TelegramApi = require('node-telegram-bot-api');

const BOT_TOKEN = process.env.BOT_TOKEN;
const bot = new TelegramApi(BOT_TOKEN, {polling: true});
// bot.setWebHook(`${process.env.URL}/bot`);

bot.on('callback_query', (query) => {
    console.log(query);
})
bot.on('message', msg => {
    console.log(msg);
})

module.exports = bot;

Again, updates with messages are recieved, but callback_query is never fired
