Reading the people column

Hi guys

I am trying to read the people column, and I am encountering an error. Please see the code below.

Query

const personsObjects = await monday.api(`query {
                            items (ids:738909449) {
                              column_values(ids: "people") {
                                ... on PeopleValue {
                                   persons_and_teams{
                                    id
                                  }
                                }
                              }
                            }
                          }`)

Response
message":"No such type PeopleValue, so it can’t be a fragment condition
