Retrieving object properties from the result fetched from mongodb in nodejs - json

Question

I'm trying to retrieve array of objects properties but I cannot retrieve any properties apart from _id in the object. But I can retrieve the whole array at once or even the individual objects inside array but not the properties that are within each object.
This is the JSON structure
[{
"_id": "5a82df96f2730d4bb177ffe1",
"project_id": 123,
"project_name": "proj11",
"tasks": [],
"links": [],
"__v": 0,
"upsert": true
}]
This the code
taskDelay(req,res) {
ProjectMaster.find({ "project_id": 123 })
.then(response => {
var result = response[0];
var resultId = response[0]._id;
var resultName = response[0].project_name;
var resultProjId = response[0].project_id;
console.log(result); // outputs the object
console.log(resultId); // outputs 5a82df96f2730d4bb177ffe1
console.log(resultName); // undefined
console.log(resultProjId); // undefined
res.status(200).send(response)
})
.catch(error => res
.status(400)
.send(error));
}
What might be the cause for showing undefined for other properties??

Finally, I found the solution for this issue. It is with the data format mongodb sending in response. I tried to do JSON.parse but it didn't work. toObject() did the trick.
taskDelay(req,res) {
ProjectMaster.find({ "project_id": 123 })
.then(response => {
var result = response[0];
var resultId = response[0]._id;
var resultName = response[0].toObject().project_name;
var resultProjId = response[0].toObject().project_id;
console.log(result); // outputs the object
console.log(resultId); // outputs 5a82df96f2730d4bb177ffe1
console.log(resultName); // outputs 123
console.log(resultProjId); // outputs proj11
res.status(200).send(response)
})
.catch(error => res
.status(400)
.send(error));
}
I did a mistake of not reading mongoose document completely! This behaviour is regarding with mongoose data formats.
