rTurk无法从Amazon Mechanical Turk获得结果

我遇到了一个非常奇怪的问题。我能够正确地向亚马逊Mechanical Turk提交HIT。我有一个cron不断检查是否有任何工作准备好进行审查。然而，当一项工作完成时，我没有收到它，但是HIT被处理掉了（在函数内部完成的工作来检查它）。奇怪的是，这个问题并不总是发生，而是经常发生。rTurk无法从Amazon Mechanical Turk获得结果

这是函数的代码审查点击：

def self.review_hits 
hits = RTurk::Hit.all_reviewable 
p "HITS" 
p hits 
puts "REVIEWABLE HITS: " + hits.count.to_s 
hits_results = {} 

unless hits.empty? 
    hits.each do |hit| 
    puts "IN EACH HIT" 
    p hit 
    results = [] 
    hit.expire! 

    # Get results for each HIT assignment 
    hit.assignments.each do |assignment| 
     # Check if the assignmment has been submitted. It can be the case where the maximum waiting time 
     # for the job to finish expired and there remain assignments that are not submitted 
     if assignment.status == 'Submitted' 
     p "STATUS 1" 
     p assignment.status 
     temp = {} 
     temp[:worker_id] = assignment.worker_id 
     temp[:answer] = assignment.answers 
     p "STATUS 2" 
     p assignment.status 
     assignment.approve! 
     results << temp 
     end 
    end 

    begin 
     hit.dispose! 
    rescue 
    end 

    hits_results[hit.id] = {} 
    hits_results[hit.id][:results] = results 
    end 

    # Let Rails know that there are new results 
    AmazonTurkHit.store_results(hits_results) 
end

端

所以放 “审查的HITS：” 是0，但HIT设置。有谁知道为什么？
