How to use the ioredis.ReplyError function in ioredis

.post((req, res) => {
    if (!req.body.email) return res.status(422).json('email not set');

    Authentication.findOne({ 'email': req.body.email })
    .then(() => {
      return randomBytes(64);
    })
    .then(buf => {
      const random = buf.toString('hex');
      // save reset code for a day
      req.uwave.redis.set(`reset:${user.req.body.email}`, random, `NX EXPIRE ${24*60*60}`);
      res.status(200).json(random);
    })
    .catch(redis.ReplyError, e => {
      log(`couldn't set reset link. Err: ${e}`);
      res.status(410).json('could not generate reset code');
    })
    .catch(e => {
      log(`error occured while generating reset code. Err: ${e}`);
      res.status(500).json('internal server error, please try again later');
    });
  })
