I'm experiencing a similar issue with child of child

const JournalSchema = new mongoose.Schema({
  message: {type: String},
}, {timestamps:true})

const ProductSchema = new mongoose.Schema({
  name: {type: String},
  journal: [JournalSchema]
}, {timestamps:true})

var LoTSchema = new mongoose.Schema({
  products: [ProductSchema],
}, {timestamps:true})

const LotsModel = mongoose.model('LoTs', LoTSchema)

const payload = {
  name: 'mock-name',
  journal: [{message: 'mock-message}]
}

  function addProductIntLot (id, payload) {
    const conditions = { _id: id }
    const update = { $push: { products: payload } }
    const options = { new: true, runValidators: true, fields: { products: { $slice: -1 } } }

    return LotsModel.model.findOneAndUpdate(conditions, update, options)
  }


journal entry never gets createdAt & updatedAt fields.

result.products[1].journal does not contain timestamps

const { default: mongoose } = require("mongoose")

const JournalSchema = new mongoose.Schema({
    message: {type: String},
  }, {timestamps:true})
  
  const ProductSchema = new mongoose.Schema({
    name: {type: String},
    journal: [JournalSchema]
  }, {timestamps:true})
  
  var LoTSchema = new mongoose.Schema({
    products: [ProductSchema],
  }, {timestamps:true})
  
  const LotsModel = mongoose.model('LoTs', LoTSchema)
  
  const payload = {
    name: 'mock-name',
    journal: [{message: 'mock-message'}]
  }
  
  async function run() {

    await mongoose.connect('mongodb://localhost:27017');
    await mongoose.connection.dropDatabase();
   const condition = await LotsModel.create({
        products: [{name: 'Test', journal: [{message: 'Testerson'}]}]
    });
    const update = { $push: { products: payload } }
    const options = { new: true, runValidators: true, fields: { products: { $slice: -1 } } }

    await LotsModel.findOneAndUpdate({_id: condition._id}, update, options);
    const result = await LotsModel.findOne();
    console.log(result.products[0]);
    console.log(result.products[1]);
console.log(result.products[1].journal);
  }

  run();

i solved it by adding createdAt and updatedAt manually. when i update my data i pass createdAt: false and updatedAt: date.now(), but i still wondering why timestamps: true won't generate those field if i use subdocument
