Bug Description

The result area are show [object Object],[object Object] instead of [{"k1": "v1"}, {"k2": "v2"}] when expression value is the array of object type.

To Reproduce

1. Go to editor canvas
2. Add 1st-node Data transformation > Edit Fields (Set)
3. Select mode json and expression then paste data below

{
  "list_of_object": [{
    "text": "Apple Pencil 2",
    "color": "White"
  }, {
    "text": "Computer Set ITX Gaming",
    "color": "Mixed"
  }, {
    "text": "DELL ALIENWARE 38 Curved Display",
    "color": "Black"
  }]
}

4. Add next node for the 2nd like the 1st one, Data transformation > Edit Fields (Set)

{
  "edit_list": {{ $json.list_of_object }}
}
