Postman post request field must not be empty

Question

{"active":true,"name":"webhook","resource":{"type":"CONTACT"}}

I'm sending this in raw body in postman but getting this eror

    "status": 422,
    "errors": [
        {
            "field": "resource.desks",
            "cause": "must not be empty"
        }

How can I add this field to body

I've tried these;

{"active":true,"name":"webhook","resource":{"type":"CONTACT", "desk":"me"}}

{"active":true,"name":"webhook","resource":{"type":"CONTACT"}, "desk":"me"}

{"active":true,"name":"webhook","resource":{"type":"CONTACT"}, "resource.desks":"me"}

{"active":true,"name":"webhook","resource":{"type":"CONTACT", "resource.desks":"me"}}

But I'm still getting the same error
