How to sort an array of objects by date in MongoDB?

Question

JavaScript

I have a collection with the following schema:

var project = new Schema({
head:{
    head_task: String,
    userID: String
},
access_users: {
    type : Array ,
    "default" : []},
context_task: [{
            from_name: String,
            status: Boolean,
            task: String,
            created_task: {
                type: Date,
                default: Date.now()
             }
        }],
created: {
        type: Date,
        default: Date.now
    }});

Tell me how to get a document sorted by the context_task.created_task field in descending order. As far as I understand, you need to use aggregation, the next query is db.tasks.aggregate({$match :{"_id":ObjectId("590e2d7d4d4a5e0b647d0835")}}, {$sort: {"context_task.created_task": -1}}). pretty(); outputs the document in the normal order, sorting does not work. Or it all needs to be done already on the client?

Yes, sorting is for documents, not their content.
