cant get property object in nodejs

Question

Product_Detail.findOne({"detail.id_product": req.params.id}, function(err, detail){
            console.log(detail)
            console.log(detail.detail)
            console.log(detail.images)               
        })

This is returned from server:

Why console.log(detail.detail) and console.log(detail.images) return undefined. ssssssssssssssssssssssssssssssssssssssssssssssssssThankssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss

Can you try logging `typeof detail` as your first console log. If its string then you will have to JSON.parse it. — surajs21, Jun 17 '20 at 04:24
Assuming this is mongoose, could you post the model definition for `Product_Detail`? — ATOMP, Jun 17 '20 at 04:26
As @atomp suggested, if its mongoose then you will not be able to get a property easily. Try doing `detail = detail.toObject()` as first thing. — surajs21, Jun 17 '20 at 04:32
@surajs21 thank you very much, i just add detail = detail.toObject() and it work — Trí Phan, Jun 17 '20 at 04:34
You may want to try one of these to improve your workflow instead of writing `toObject()` everywhere https://stackoverflow.com/questions/7503450/how-do-you-turn-a-mongoose-document-into-a-plain-object — ATOMP, Jun 17 '20 at 04:40

Assuming it to be a mongoose code, you can not get property easily. Can you try this

Product_Detail.findOne({"detail.id_product": req.params.id}, function(err, detail){
    detail = detail.toObject(); // this

    console.log(detail)
    console.log(detail.detail)
    console.log(detail.images)              
})
