Mongodb 如果响应期间不是函数，则类型错误seneca indexof

我编写了一个简单的操作，它使用seneca mongo store模块连接到mongo db，执行列表查询并获得结果。我可以看到查询成功了，并且获取了正确的结果。当我尝试将这些结果发送回客户机时，响应调用错误会显示以下消息和堆栈跟踪

ERROR       act     root$           OUT             cmd:getparams,role:diff 11      {cmd:getparams,role:diff,payload:{id:scalaScan}}    ENTRY    (dqk22) -       seneca: Action cmd:getparams,role:diff callback threw: k.indexOf is not a function.     act_callback    {message:k.indexOf is not a function,pattern:cmd:getparams,role:diff,instance:Seneca/0.7.2/d0twcki9cmxg/1485517      TypeError: k.indexOf is not a function

同样的代码也在工作，现在我得到了这个错误。不知道发生了什么变化。非常感谢您的帮助/建议

我所面临的问题是因为模块js文件中的这段代码

if( _.isObject( result.out ) ) {
    _.each(result.out,function(v,k){
      if(~k.indexOf('$') && 'http$' !== k) {
        delete result.out[k]
      }
    })

每个函数都要解析一个JSON对象，在我的例子中，out实际上是一个JSON数组。将数组包装到对象中可以解决此问题

if( _.isObject( result.out ) ) {
    _.each(result.out,function(v,k){
      if(~k.indexOf('$') && 'http$' !== k) {
        delete result.out[k]
      }
    })
