Dot operator not fetching child properties of a Mongoose Document object

[laggingreflex]

I have a mongoose schema less schema

var User = new mongoose.Schema({}, {
    strict: false,
});

and any object I save with it, seems to contain the properties that I saved

console.log(user); /* =>
{ username: 'user1',
  salt: '3303187e50a64889b41a7a1c66d3d3c10b9dec638fdd033bee1221d30d01c5e1',
  hash: 'a174c206d88bee1594bb081dbd32d53420f6ef3d6322104f3d0722d58bc8dd8d',
  _id: 52d3177481daf59c11000001,
  __v: 0 } */

but when I try to access those properties individually with a dot operator, it outputs undefined!!

console.log(user.hash); // => undefined

What could be causing this?

This only happens with the properties that aren't declared in the schema. If I declare hash in the schema it works. Is this by design? (that you can't access schema-less properties) And even if so, how is it even achieved - not allowing access properties with dot operator?

Hmm this may be a bug with unstrict schemas. Can you tell me what version of mongoose you're using?

I'm using 3.8.17
