I am using the below graphQL req to retrieve assetes updates records

{
  updates(page: 1, limit: 100) {
    assets {
      created_at
      file_extension
      file_size
      id
      name
      original_geometry
      public_url
      uploaded_by {
     
        id
        
      }
      url
      url_thumbnail
    }
  }
}

I have observed that this API throws an error for uploaded_by field, throwing a null empty array

{
        "assets": [
          null,
          null,
          null
        ]
      },
      {
        "assets": [
          null,
          null,
          null
        ]
      }

and the error message: “message”: “Cannot return null for non-nullable field Asset.uploaded_by”
is this the expected behaviour?
