Exclude some sub-properties using mongoose

Question

Hi every one.
I'm using mongoose and I want to exclude two sub properties (description and userId) from final result.
If this is the code 👇, how can I exclude this two properties (after populate it)?
As you see, I used select method for this reason, but the result still includes these two properties.
How can I resolve this?

thanks for your help.

I believe ->
To exclude the description and userId properties after populating a field in Mongoose, you can use the select method in your .populate() call, but make sure you're excluding the fields correctly.

const getOrders = async (userId) => {
try {
const orders = await Order.find({ userId: userId })
.populate("items.product", "-description -userId") // Exclude 'description' and 'userId'
.exec();
console.log(orders);
return orders;
} catch (err) {
console.error(err);
throw err;
}
};
