Populate hook with array of one ref return object not an array.

[ducnvhn]

Steps to reproduce

Here is my post schema in mongodb :

...
comments: [ {type: Schema.Types.ObjectId, ref: 'Comment'}]  //array of ref to comment
...

and the populate schema in the feather hook

const populateCommentSchema = {
 include: [
   service: 'comments',
   nameAs: 'comments',
   parentField: 'comments',   //the field in the Post schema
   childField: '_id'    //the field in the Comment schema
 ]
};

The post hook object:

const postHooks = {
  .....
  after: {
    ...
    find: [populate({ schema: populateCommentSchema  })]
    ...
  }
}

Expected behavior

when I try to populate Comments when calling find service method , the result should contain an array of Comments.

Actual behavior

But if the Post have just one ref of Comment in the array, the result of comments is just one object.

Did I made the wrong populate schema ? or something I missed along the way ? Please point me out.
Thank you very much.
