Check this question. Mongo returns an object, the best way is to acces value in the lenguage you use.J.F.– J.F.2021-01-23 18:29:02 +00:00Commented Jan 23, 2021 at 18:29

Using mongoose you can do this using findOne:
yourModel.findOne({level:3},{id:1}).then(result => {
console.log("result = ",result.id)
}).catch(e => {
// error
})
Response is 553
Example how mongo query works here. This example output an array but ising findOne only one value will be returned, so you can do response.name directly and get the value.
