Cast to number failed for value "[object Object]" at path "undefined"

[Matt Clark]

I have this schema:

var Photo = new Schema({

     URL:String

    ,description:String

    ,created_by:{type:ObjectId, ref:'User'}

    ,created_at:{type:Date, default:Date.now()}

});

var User = new Schema({

    name:{type:String,index:true}

    ,email:{type:String,index:true, unique:true}
});

//Task model                                                                                                                                                                                       

var Task = new Schema({

    title:String

   ,created_by:{type:ObjectId, ref: 'User'}

   ,created:{type:Date, default:Date.now()}

   ,responses:[{

       type:Number

      ,user:{type:ObjectId, ref: 'User'}

       ,comment:String

       ,avatarURL:String

       ,photo:{type:ObjectId, ref: 'Photo'}

      ,created:{type:Date, default:Date.now()}

   }]

});

//Group model                                                                                                                                                                                      

var Group = new Schema({

     name:String

    ,tasks:[Task]

});

and this code errors out (group is fine, task at that idx is fine,responses is an empty array,user is valid,photo is valid):

 

var typePhoto = 6;
 var resp = {
      type: typePhoto//photo                                                                                                                                                
      ,user: user._id
      ,photo: photo._id
 };


 group.tasks[taskIdx].responses.push(resp); //errors out here

at that point I get the following error:

/home/admin/notitws/node_modules/mongoose/lib/utils.js:434

        throw err;

              ^

Any ideas on how to fix this or what may be causing it?

Thanks!

PS Don't know if it matters but in the call to get group I am populating tasks.responses.user and tasks.responses.photo and tasks.created_by.

fixed it was the "type:Number" should have been "type:{type:Number}"
