Deep nested query

I have 3 models
Publications → User → Validation

And an endpoint /publications/fromUsersIFollow

When I make a request, I get all the publications data and almost all Validation data

(publication) { user:{ validation:id } }
and what I want is
(publication) { user:{ validation:{ } } }
I tried the populated thing
let publications = await,["user.validation"])
But still brings the instead of the object.

What I’m missing or doing wrong?
