nothing append when using answerInlineQuery to send photo.

Here is my code, very basic:

bot.on('inline_query', function(query) {
  picturesToSend = [];
  // open the folder and get the number of pictures in
  var files = fs.readdirSync('./img/');
  var numberOfPics = files.length;

  // get 3 random pictures from my folder
  for (var i = 0; i < 3; i++) {
    // get a random picture name in my folder
    pictureName = files[Math.floor(Math.random() * numberOfPics)];
    // open this picture and add it to and array
    picturesToSend.push(fs.readFileSync('./img/' + pictureName));
  }
  // send the array containing 3 pictures
  bot.answerInlineQuery(query.id, picturesToSend);
});

When using answerInlineQuery nothing append and I got no error. Of course I have activate /setinlineBot with botfather

Your code is wrong. Take a look on answerInlineQuery

Thank you for your help. For now it’s not possible to send local file.
