Web app Telegram.WebApp.sendData event on bot's side

[nightrider77]

I am trying to send some data in my web app to my bot:

Telegram.WebApp.sendData("test_data");

But I don't see any event on bot's side, like "message" or "callback_query" with my data inside.

Am I missing something?

const TelegramBot = require('node-telegram-bot-api');
const TOKEN = 'YOUR_BOT_TOKEN'; 
const bot = new TelegramBot(TOKEN, { polling: true });

// Handle /start command to send an initial message
bot.on('message', (msg) => {
  if (msg.text.toString() === '/start') {
    bot.sendMessage(msg.chat.id, 'Hello! Click the button below to send data from the Web App.', {
      reply_markup: {
        inline_keyboard: [
          [{ text: 'Send Data', callback_data: 'get_web_app_data' }],
        ],
      },
    });
  }
});

// Handle the callback query from the button
bot.on('callback_query', (query) => {
  if (query.data === 'get_web_app_data') {
    const webAppData = query.message.web_app_data; // Access data here!
    bot.sendMessage(query.message.chat.id, `Web App Data: ${webAppData?.data}`);
  }
});

maybe only work in 'keyboard' but not 'inline_keyboard'
