Trying to create leave allocation based on a field in hr.employee model.
    @api.onchange('confirm_date')
    def _onchange_confirm_date(self):
        if self.confirm_date:
         
            # Create sick leave allocation
            self.env['hr.leave.allocation'].create({
                'name': 'Automatic Sick Leave Allocation',
                # 'holiday_status_id':
 self.env.ref('hr_holidays.holiday_status_sl').id,
                'holiday_status_id': 1,
                'holiday_type': 'employee',
                # 'employee_ids': [(4, self.id)],
                'employee_ids': 20,
                'employee_company_id': 1,
                'department_id': 3,
	​	​     	​'number_of_days': 15.0,
                'state': 'draft',
                'allocation_type': 'regular',
                'date_from': '2024-01-21',
                'date_to': '2024-12-21',
            })

it's giving me the validation error: 
The employee, department, company or employee category of this request is missing. Please make sure that your user login is linked to an employee.

Here is the sql constraints causing the error:


    _sql_constraints = [
        ('type_value',
         "CHECK( (holiday_type='employee' AND (employee_id IS NOT NULL OR multi_employee IS TRUE)) or "
         "(holiday_type='category' AND category_id IS NOT NULL) or "
         "(holiday_type='department' AND department_id IS NOT NULL) or "         "(holiday_type='company' AND mode_company_id IS NOT NULL))",
         "The employee, department, company or employee category of this request is missing. Please make sure that your user login is linked to an employee."),
        ('duration_check', "CHECK( ( number_of_days > 0 AND allocation_type='regular') or (allocation_type != 'regular'))", "The duration must be greater than 0."),
    ]

what am i doing wrong here?
