Problem with adding a child to a tree

[dreamfall]

Hi, I'm having troubles with adding a record as a child in tests:

defmodule SomeApp.Api.Node do
  use Ecto.Schema
  use AsNestedSet, scope: [:emotion_id]
end


root_node = %Node{emotion_id: emotion.id, name: "root"} |> AsNestedSet.create(:root) |> AsNestedSet.execute(Repo)
child_node = %Node{emotion_id: emotion.id, name: "asd"} |> AsNestedSet.create(root_node, :child) |> AsNestedSet.execute(Repo)
      
IO.inspect root_node
IO.inspect child_node

# root node, works fine, lft and rgt are calculated
%SomeApp.Api.Node{
  __meta__: #Ecto.Schema.Metadata<:loaded, "nodes">,
  emotion_id: 65,
  id: 96,
  inserted_at: ~N[2022-03-31 09:10:34],
  lft: 0,
  name: "root",
  parent_id: nil,
  rgt: 1,
  updated_at: ~N[2022-03-31 09:10:34]
}
# supposed to be a child of root node, but it's not
%SomeApp.Api.Node{
  __meta__: #Ecto.Schema.Metadata<:loaded, "nodes">,
  emotion_id: 65,
  id: 97,
  inserted_at: ~N[2022-03-31 09:10:34],
  lft: nil,
  parent_id: nil,
  rgt: nil,
  updated_at: ~N[2022-03-31 09:10:34]
}

Am I missing something? Seemingly two identical ways of creating an entity in the tree behave differently. If I create a child node as another root first and move it, it works, but creating it as a child right away does not seem to be working.
