Dear all,
I have a when Generate Payslip for employee when Employee creates two leave with two time off types.
For example:
- A leave with time off types is Paid time off from 8:00am to 10:00am and another leave from 10:00am to 1:00pm (Time off types is Sick time off).
Both vacations are for 1 day.
When Generate Payslips for that employee, there is ValueError: Expected singleton: hr.leave.type(1, 7)

File "/home/developer/Desktop/tvs_project/odoo16_base_addons/addons/web/controllers/dataset.py", line 33, in _call_kw return call_kw(request.env[model], method, args, kwargs) File "/home/developer/Desktop/tvs_project/odoo16_base_addons/odoo/api.py", line 461, in call_kw result = _call_kw_multi(method, model, args, kwargs) File "/home/developer/Desktop/tvs_project/odoo16_base_addons/odoo/api.py", line 448, in _call_kw_multi result = method(recs, *args, **kwargs) File "/home/developer/Desktop/tvs_project/third_app/om_hr_payroll/wizard/hr_payroll_payslips_by_employees.py", line 25, in compute_sheet slip_data = self.env['hr.payslip'].onchange_employee_id(from_date, to_date, employee.id, contract_id=False) File "/home/developer/Desktop/tvs_project/third_app/om_hr_payroll/models/hr_payslip.py", line 463, in onchange_employee_id worked_days_line_ids = self.get_worked_day_lines(contracts, date_from, date_to) File "/home/developer/Desktop/tvs_project/third_app/om_hr_payroll/models/hr_payslip.py", line 209, in get_worked_day_lines 'name': holiday.holiday_status_id.name or _('Global Leaves'), File "/home/developer/Desktop/tvs_project/odoo16_base_addons/odoo/fields.py", line 1132, in __get__ record.ensure_one() File "/home/developer/Desktop/tvs_project/odoo16_base_addons/odoo/models.py", line 5119, in ensure_one raise ValueError("Expected singleton: %s" % self) ValueError: Expected singleton: hr.leave.type(1, 7)

Please share the code of your Function that is causing the error.

The function is recieving two records. But it expects only one record. You just have to make a slight change in the loops of your function.

Hi  ​Nam Nguyen Phuong,

It's a bug with the third-party app you installed named 'om_hr_payroll'. You can check whether the author solved the issue by pulling the latest code.
