Как удалить найденную запись из б.д?

Commands.find({ 'device': req.body.id })
  .exec()
  .then(cmd => {
    if(cmd[0]){
      Commands.remove({ 'device' : req.body.id })
        .exec()
        .then(result => {
        res.status(200).json({
          "commands": [ cmd[0].commands ],
          "result":"ok",
        });
      })
    } else {
      res.status(200).json({
        "result":"no",
      });
    }
  })
  .catch(err => {
    console.log(err);
    res.status(500).json({
      error: err
    });
  });

Commands.findOne({ device: req.body.id })
  .exec()
  .then(cmd => {
    if (!cmd) {
      throw new Error('Not found');
    }

    return cmd;
  })
  .then(cmd => Commands.deleteOne({ _id: cmd._id }).exec().then(() => cmd))
  .then(cmd =>
    res.status(200).json({
      commands: cmd.commands,
      result: 'ok',
    }),
  )
  .catch(err => {
    console.log(err);
    res.status(500).json({
      error: err,
    });
  });
