How to get video as response from youtube-dl?

I am writing a telegram bot to download a video from YouTube, I use the youtube-dl api, and when I try to get a video as response, but the video simply downloads to the root directory, but the script doesnt send it to the user, it gives me an error.

Error type:

Test video sending

There is my code:

const telegramApi = require("node-telegram-bot-api");
const token = "myApi";
const fs = require("fs");
const youtubedl = require("youtube-dl-exec");

const bot = new telegramApi(token, { polling: true });


const start = () => {
  bot.on("message", async (msg) => {
    const text = msg.text;
    const chatId = msg.chat.id;
    const mode = "youtube";

    if (text === "/start") {
      await bot.sendSticker(
        chatId,
        "https://tlgrm.ru/_/stickers/b50/063/b5006369-8faa-44d7-9f02-1ca97d82cd49/1.webp"
      );
      await bot.sendMessage(chatId, "Пошла жара...");
    }
    if (mode === "youtube") {
      console.log("Test video sending");
      const video = await youtubedl(text, {
        noWarnings: true,
        preferFreeFormats: true,
      }).then((output) => console.log(output));
      bot.sendMessage(chatId, output);
    }
  });
};

start();

What am I doing wrong?

P.S. Ignore the mode variable, this is in case I want to add other services besides youtube.

UPD.: If i write bot.sendMessage(chatId, output)

It gives a response in telegram:

Did you try to use sendVideo method? It support mp4 file format - see more here https://github.com/yagop/node-telegram-bot-api/blob/release/doc/api.md#TelegramBot+sendVideo

Also, the output variable is undefined casue it is in different scope. You should put bot.sendX call in the callback where you have a console.log funciton, so:

}).then((output) => {
 console.log(output)
 bot.sendMessage(chatId, output); // or sendVideo
});
