Why does findOne() return undefined?

Question

MongoDB

Hello!
I can’t understand, maybe someone has encountered such a problem,
why findOne () returns undefined?
When I just write lastOrder in the console, everything is fine (there is orderData and inside order: 3 )

module.exports.create = async (req, res) => {
    try {
        let lastOrder = await Order
            .findOne({user: req.user.id})
            // .sort({date: -1})
             console.log(lastOrder);

When I write lastOrder.orderData in the console, everything is fine (there is an order: 3 inside )

And when I write lastOrder.orderData.order in the console , then undefined

How can I get the order value ?
Tell me please.

orderData array, you need to specify the index
lastOrder.orderData[0].order
