This is an alternative usage to ctx.updatesubtypes AKA getting message type in telegraf 3.

bot.use((ctx, next) => {
    console.log(`Message Type is: ${getMessageType(ctx.message)}`); 
    // Message Type is: STICKER or Message Type is: TEXT
});

const getMessageType = (message) => {
    var keys = Object.keys(message);
    var messageType = keys.pop();
    console.log(messageType);
    return messageType.toUpperCase();
};

good, but not always the last **key** is **text** : `keys.pop()` — Shakiba Moshiri, Sep 29 '21 at 20:45

A good alternative to using ctx.updatesubtypes in 4.6.0 is:

bot.use((ctx, next) => {
  let message_type = "";
  let keys = Object.keys(ctx.message);
  
  if (keys.includes("text")) {
    message_type = "text";
  } else if (keys.includes("sticker")) {
    message_type = "sticker";
  } else if (keys.includes("photo")) {
    message_type = "photo";
  }
  console.log(`Message Type is: ${message_type}`);
  next();
});
