I tried to add the Employee_ID:

col = Collection();
col.insert("recordid":id);
col.insert("Date_Check_Approval":zoho.currentdate);
col.insert("Employee_ID":"9994");
info zoho.people.update("P_Leave",col.toMap());
return "success";

{
  "response": {
    "message": "Error occurred",
    "uri": "/api/forms/json/P_Leave/updateRecord",
    "errors": {
      "code": 7016,
      "message": "Invalid value '9994' for the field 'Employee_ID'"
    },
    "status": 1
  }
}
