MongoDB - Query nested objects in nested array

I'm kindly requesting your help for this query that I need to do and I'm not very proficient yet in MongoDB. My data structure looks like this:
db.getCollection('EventDateValidation').find({}):
/* 1 */
{
"_id" : ObjectId("5b7b2e3ae5e2100007717d81"),
"_class" : "com.overwatch.common.model.EventDateValidation",
"caseNo" : "OW000002269122201810201135",
"loanNo" : "000002269122",
"eventType" : "BREACLETTR",
"validationStepData" : [
{
"startDate" : {
"isChecked" : "Y",
"comments" : "",
"auditedBy" : "Mahalakshmi M",
"auditedDate" : "2018-12-12"
}
},
{
"completedDate" : {
"isChecked" : "Y",
"comments" : "",
"auditedBy" : "Mahalakshmi M",
"auditedDate" : "2018-12-13"
}
},
{
"deadlineDate" : {
"isChecked" : "Y",
"comments" : "",
"auditedBy" : "Mahalakshmi M",
"auditedDate" : "2018-12-13"
}
}
]
}
/* 2 */
{
"_id" : ObjectId("5b7c11095c2b4d0007bc8c54"),

}
},

}
}

"auditedDate" : "2018-09-25"
}
},
{

"isChecked" : "Y",
"comments" : "",
"auditedBy" : "Brett Scott",
"auditedDate" : "2018-09-25"
}
}
]
}
From this collection, I need to find the documents that have an "auditedDate" in the "deadlineDate". In this example, I would find the documents 1 and 3. Please help me as I'm stuck on this one.
I have tried
db.getCollection('EventDateValidation').find({"validationStepData.deadlineDate.auditedDate":{$exists:true}})
But doesn't seem to work. Help please!

Just for clearing things up: the query in the question works well. I chatted with #Gabriel, and the problem was that Robomongo added hidden non-printable unicode characters to the query.
All in all, for any interested nomads, here are few ways to query an array of objects:
1) Implicit $elemMatch / simple dot notation on an array:
db.getCollection('EventDateValidation').find({"validationStepData.deadlineDate.auditedDate": {$exists:true}})
2) Explicit $elemMatch (we can have multiple query criteria):
db.getCollection('EventDateValidation').find({"validationStepData": { $elemMatch: {"deadlineDate.auditedDate" : {$exists:true} }}})
3) Array dot notation with an index position (when we know the exact position of an element inside an array):
db.getCollection('EventDateValidation').find({"validationStepData.2.deadlineDate.auditedDate": {$exists:true}})

Dot notation wouldn't work since you have an array of objects within validationStepData. You could use $elemMatch to apply your query conditions to the array elements that match your expression.
db.getCollection('EventDateValidation').find({"validationStepData" : { $elemMatch: {"deadlineDate.auditedDate" : {$exists:true} }}})

MongoDB converting from int32 to double itself

I am getting a weird problem when I run in shell for mongoDB.
My collection structure is like below in mongoDB.The type of ServiceList items must be integer.
{
"_id" : ObjectId("56565"),
"Contact" : "",
"Email" : "",
"AppList" : [
{
"Code" : "",
"Usage" : NumberInt(542),
"LicenceType" : "Monthly",
"CreatedDate" : ISODate("2015-07-29T06:15:20.520+0300"),
"ServiceList" : [
1,5,8
]
}
]
}
My aim to run this code is converting Usage type from int32 to int64.It works fine.When I run the code below. something weird occours, and the type of the items inside AppList.ServiceList is converted to double from int32 itself.
db.CustomerInfo.find({}).forEach( function (item) {
if(item.AppList != undefined){
item.AppList.forEach(function (x){
x.Usage = NumberLong(x.Usage);
});
db.CustomerInfo.save(item);
}
});
and it seems like this,
{
"_id" : ObjectId("56565"),
"Contact" : "",
"Email" : "",
"AppList" : [
{
"Code" : "",
"Usage" : NumberLong(542),
"LicenceType" : "Monthly",
"CreatedDate" : ISODate("2015-07-29T06:15:20.520+0300"),
"ServiceList" : [
1.0,5.0,8.0
]
}
]
}
How can I solve this problem ?

Mongoose (MongoDB) - Error: Can't use $each with Number

I've to push a given array of Number values into a selected Document inside my MongoDB database.
The Document that I'm going to update as the following structure:
{
"_id" : {
"id" : 17,
"type" : "f"
},
"__v" : 0,
"created_at" : ISODate("2017-03-22T11:16:21.403Z"),
"token" : {
"expDate" : ISODate("2017-12-31T00:00:00Z"),

},
"updated_at" : ISODate("2017-07-24T09:42:33.741Z"),

]
},

{
"idPlotBind" : 1,
"ip" : "",
"mac" : "18-5F-00-4A-FE-F4",
"irrId" : 31,
"_id" : ObjectId("59084f527d634d301338aac6"),

},

"irrId" : 35,
"_id" : ObjectId("59084f7d7d634d301338aac7")
}
]
}
I'm using the Mongoose library for JS, and the accused query is this one:
userSchema.findOneAndUpdate({$and:[{ '_id.id': resData.PlotRows.IdUser}, {'_id.type': 'f'}]},{$addToSet:{'plots.$.idPlot': {$each: plotData}}}, {upsert: false}, function(err, usr){
if(err){
console.log(err);
return;
}
});
But when I try to execute it, gives me back:
Error: Can't use $each with Number

So as you can see this is the single document that contains the whole data of array i want to fetch the orders whose status is cancel from this order array.
So for that i have use :-
var orderDetails =
orders.find({"ListOrdersResult.Orders.Order":{$elemMatch:
{ OrderStatus:"Canceled"}}}).fetch();
Also i tried with:-
orders.find({"ListOrdersResult.Orders.Order.OrderStatus":'Canceled'}).fetch();
So this will return the whole document that contains status as canceled and other as well but i want only selected result from the document that contains status as pending.
So is there any way in mongoDb to query a selected value from a single document that contains nested array of arrays as object.
Or I need to staore the values into diff diff documents thats only the solution.
Any help would be appriciated please contribute
Thanks!

You can go with any meteor aggregate package. You can use match and then group the data then send it to client-side.Like :
var ordersLines = orders.aggregate([
{$unwind : "$ListOrdersResult.Orders.Order"},
{$match : { OrderStatus:"Canceled"} },
{$project : {
OrderType : '$ListOrdersResult.Orders.Order.OrderType'
....
}
}
]);
return ordersLines;
But I suggest you go with a different document.

MongoDB .find() only ObjectId's embedded in an Array.

I am trying to get only the ObjectId's from One specific Document that is embedded in the projects Array.
Basically I am trying to make a database that will have users and each user will have there own projects.
Thank you !
db.users.find().pretty()
{
"_id" : ObjectId("5762c0cf2b9a78006373a684"),
"name" : "seq",
"pass" : "seq",
"projects" : [
{
"pid" : ObjectId("5762c0ba2b9a78006373a682"),
"name" : "aaa"
},
{
"pid" : ObjectId("5762c0ba2b9a78006373a683"),
"name" : "bbb"
}
]
}
{
"_id" : ObjectId("5762c28d2b9a78006373a687"),
"name" : "leq",
"pass" : "leq",
"projects" : [
{
"pid" : ObjectId("5762c2892b9a78006373a685"),
"name" : "ccc"
},
{
"pid" : ObjectId("5762c2892b9a78006373a686"),
"name" : "ddd"
}
]
}

let say we want two pids
{"pid" : ObjectId("5762c0ba2b9a78006373a682")} and
{"pid" : ObjectId("5762c2892b9a78006373a686"),}
and only inner documents
so required response should look like:
{
"_id" : ObjectId("5762c0ba2b9a78006373a682"),
"name" : "aaa"
},{
"_id" : ObjectId("5762c2892b9a78006373a686"),
"name" : "ddd"
}
Aggregation framework can manipulate documents, match only needed ones and transform inner structure by project phase:
var match = {
$match : {
"projects.pid" : {
$in : [ObjectId("5762c0ba2b9a78006373a682"),
ObjectId("5762c2892b9a78006373a686")]
}
}
}
var unwind = {
$unwind : "$projects"
};
// now move array objet as top level object
var project = {
$project : {
_id : "$projects.pid",
name : "$projects.name",
// list other fields here
}
}
db.vic.aggregate([match, unwind, match, project])
