No customFields in GET "List tasks by ticket"

Hello,

i use the New Zoho Desk API to get all Tasks from one Ticket.
https://desk.zoho.com/DeskAPIDocument#Tasks#Tasks_Listtasksbyticket

There was a Response example:

{
  "data" : [ {
    "modifiedTime" : "2016-07-14T08:22:16.000Z",
    "customFields" : {
    },
    "subject" : "New Testing Task",
    "departmentId" : "3000000007043",
    "dueDate" : "2016-07-21T16:16:16.000Z",
    "creatorId" : "3000000008692",
    "description" : null,
    "ownerId" : null,
    "priority" : "Normal",
    "createdTime" : "2016-07-14T08:22:16.000Z",
    "id" : "3000000053002",
    "category" : "null",
    "ticketId" : "3000000008753",
    "status" : "In Progress"
  } ]
}

With "customFields" in it, but wenn i make a GET Call, there arent CustomField in there.
How can i get these fields, too?

My Response:

Kind Regards,
Klaus Brandt
