kue invalid job使nodejs转储

Question

kue扔了错误：

content:  Error: job "121308" is invalid

nodejs app退出意外。 我引用了代码并且不知道原因。

/**
 * Get job with `id` and callback `fn(err, job)`.
 *
 * @param {Number} id
 * @param {String} jobType is optional
 * @param {Function} fn
 * @api public
 */

exports.get = function( id, jobType, fn ) {
  if (id === null || id === undefined) {
    return fn(new Error('invalid id param'));
  }
  if (typeof jobType === 'function' && !fn) {
    fn = jobType;
    jobType = '';
  }
  var client = redis.client()
    , job    = new Job;

  job.id = id;
  job.zid = client.createFIFO(id);
  client.hgetall(client.getKey('job:' + job.id), function( err, hash ) {
    if( err ) return fn(err);
    if( !hash ) {
      exports.removeBadJob(job.id, jobType);
      return fn(new Error('job "' + job.id + '" doesnt exist'));
    }
    if( !hash.type ) {
      exports.removeBadJob(job.id, jobType);
      return fn(new Error('job "' + job.id + '" is invalid'))
    }
.....
 

有人问过这个问题吗？
