I try to run this code, s2_obj = @from i in df_recipe begin @let ibu_cs = (i.ibu - cs_dict["m_ibu"]) / cs_dict["sd_ibu"] @let color_cs = (i.color - cs_dict["m_color"]) / cs_dict["sd_color"] @select {id = i.id, ibu = ibu_cs, color = color_cs} @collect DataFrame end But get this error type NamedTup…

Type NamedTuple has no field id
