Hello,

you should convert your start date (string type) into date type. (datetime.strptime)

For ref. see below code.

1) import libraries

from odoo.tools import DEFAULT_SERVER_DATE_FORMAT

from datetime import datetime


2) replace your method with this method in your code

                @api.onchange('name', 'start_date')

                def _change_date(self):

                    if self.name == 'STNK' and self.start_date:

                        date_start = datetime.strptime(self.start_date, DEFAULT_SERVER_DATE_FORMAT)

                        self.end_date = date_start + relativedelta(years=5)


Thanks,

Dipak
