Zoho Leave API invokeurl returns error code 7019 "Missing parameter(s) in the request"

Hi,

I executed this in Zoho Flow to update a Leave Record in Zoho People :-
========================================
UpdateLeaveRecord = invokeurl
[
url :"https://people.zoho.com/people/api/forms/json/leave/updateRecord"
type :POST
parameters:UpdateRecord.toMap()
connection:"internal--zohopeople"
];
========================================

I received the following reply :-
========================================
"response": {
"message": "Error occurred",
"uri": "/api/forms/json/leave/updateRecord",
"errors": {
"code": 7019,
"message": "Missing parameter(s) in the request"
},
"status": 1
}
========================================

An example of the parameters passed in this command (values removed) :-
========================================
{
	"customUpdateLeaveRecord_27": {
		"GCalID": "xxxxxxxxxxxxxxxxxxxx",
		"Employee_ID": "xxxxxxxxxxxxxxxxxxxx",
		"DayDetails": {
			"05-Jul-2021": {
				"LeaveCount": 0.5,
				"Session": 1
			}
		},
		"Leavetype.ID": xxxxxxxxxxxxxxxxxxxx,
		"From": "05-Jul-2021",
		"Unit": "Day",
		"ApprovalStatus": "Pending",
		"Daystaken": 0.5,
		"Reasonforleave": "",
		"TeamEmailID": "",
		"Leavetype": "No Pay Leave",
		"To": "05-Jul-2021",
		"Employee_ID.ID": xxxxxxxxxxxxxxxxxxxx,
		"DateOfRequest": "16-May-2021"
	}
}
========================================


I obtained the template for the keys and values for Leave record above by executing a GET command and following the formats exactly.

Anyone can assist to highlight what other parameters are required to update a Leave record successfully?

Thanks in advance!

Best regards,
