Unable to download file via Google Drive API

Node.js v10.15.2, googleapis v40.0.0

I tried this

  const dest = fs.createWriteStream(`/Users/user/Downloads/${fileId}.mp4`);
  drive.files.get({
    fileId,
    alt: 'media'
  },
  {
    responseType: 'stream'
  }, (err, res) => {
    res.data.on('end', () => {
      console.log('Done downloading file!');
    })
    .on('error', console.error)
    .pipe(dest);
  });

And got error

Also, I tried this example from Google API reference.

    const dest = fs.createWriteStream(`/Users/user/Downloads/${fileId}.mp4`);
    drive.files.get({
      fileId,
      alt: 'media'
    })
      .on('end', function () {
        console.log('Done');
      })
      .on('error', function (err) {
        console.log('Error during download', err);
      })
      .pipe(dest);

And got error

I list file 20140810_125633.mp4 successfully but can't download it. What am I doing wrong?

All the code I have

const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');

// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
const TOKEN_PATH = 'token.json';

// Load client secrets from a local file.
fs.readFile('credentials.json', (err, content) => {
  if (err) return console.log('Error loading client secret file:', err);
  // Authorize a client with credentials, then call the Google Drive API.
  authorize(JSON.parse(content), listFiles);
});

/**
 * Create an OAuth2 client with the given credentials, and then execute the
 * given callback function.
 * @param {Object} credentials The authorization client credentials.
 * @param {function} callback The callback to call with the authorized client.
 */
function authorize(credentials, callback) {
  const {client_secret, client_id, redirect_uris} = credentials.installed;
  const oAuth2Client = new google.auth.OAuth2(
      client_id, client_secret, redirect_uris[0]);

  // Check if we have previously stored a token.
  fs.readFile(TOKEN_PATH, (err, token) => {
    if (err) return getAccessToken(oAuth2Client, callback);
    oAuth2Client.setCredentials(JSON.parse(token));
    callback(oAuth2Client);
  });
}

/**

 * execute the given callback with the authorized OAuth2 client.
 * @param {google.auth.OAuth2} oAuth2Client The OAuth2 client to get token for.

 */
function getAccessToken(oAuth2Client, callback) {
  const authUrl = oAuth2Client.generateAuthUrl({
    access_type: 'offline',
    scope: SCOPES,
  });
  console.log('Authorize this app by visiting this url:', authUrl);
  const rl = readline.createInterface({

In API v3 you get a promise from "drive.files.get" and on the promise resolve you have the "data" stream

function downloadFile(drive, fileId, fileName) {
  const filePath = `/Users/user/Downloads/${fileName}`;
  const dest = fs.createWriteStream(filePath);
  let progress = 0;

  drive.files.get(
    { fileId, alt: 'media' },
    { responseType: 'stream' }
  ).then(res => {
    res.data
      .on('end', () => {
        console.log('Done downloading file.');
      })  
      .on('error', err => {
        console.error('Error downloading file.');
      })  
      .on('data', d => {
        progress += d.length;
        if (process.stdout.isTTY) {
          process.stdout.clearLine();
          process.stdout.cursorTo(0);
          process.stdout.write(`Downloaded ${progress} bytes`);
        }   
      })  
      .pipe(dest);
  }); 
}
