API v2 - change people column error 500

Good morning, i am trying the api v2 from “the try it yourself” editor, sending this mutation:
mutation {
change_multiple_column_values (board_id: xxxx, item_id: xxxxx, column_values: “{“stato”: {“label”: “Working on it”},“timeline”:{“from”:“2019-06-03”,“to”:“2019-06-07”},“data”:{“date”:“2019-06-03”},“persone”:{“personsAndTeams”:[{“id”:xxxxx,“kind”:“person”}]}}”) {
id
}
}
i get back an internal server error code 500, if i remove this part:
,\"persone\":{\"personsAndTeams\":[{\"id\":xxxxx,\"kind\":\"person\"}]}

then it work fine.
where is the mistake?
thanks

seems like the correct mutation. can you make sure “persone” column is a multiple person column and not a person column?
you can use this query to do so:

boards(ids:xxx){
  columns{
    title
    type
    id
  }
}

this is the response:
{
“title”: “Persone”,
“type”: “multiple-person”,
“id”: “persone”
},

Hey @abalest14 – thanks for sending that over.

Let’s solve this over a ticket. I just sent you a direct message following up.

Cheers,
