Mongoose select specific fields from array elements

Question

Let's say I have this schema

{
jedi: [{
       name:String
       lightsaber_color:String
      ]}
}

I want to return all and only the names of them. I tried

Jedi.find({})
    .select('jedi.name')
    .exec(function (err, jedi) {
      if (err) {
        console.log("nothing found")
      }
}

It returns me nothing, while this code returns me everything.

Jedi.find({})
        .select('jedi')
        .exec(function (err, jedi) {
          if (err) {
            console.log("nothing found")
          }
    }

I see that jedi is an array so I think that .select('jedi.name') may not work for this reason.
What is the right syntax to do so?

You can try with this

Jedi.find({}, {'jedi.name':1}, function (err, jedi) {
      if (err) {
        console.log("nothing found")
      }
      else{
        console.log(jedi);
      }
}
