Zoho Desk API Custom Module not all data is showing up

Zoho Desk API Custom Module not all data is showing up

When i get a record by id for my new module:

responseDetailed = invokeurl
[
url :"https://desk.zoho.eu/api/v1/cm_tickets_CM/" + record.getJSON("id") 
type :GET
parameters:""
connection:"desk_connection"
];

The response doesnt contain all fields, the field im missing is the contact and customer.
