Hi,
In odoo 13 , your inheriting  the below onchange function from *res_partner* model,
@api.onchange('state_id')
def *_onchange_state*(self):
if self.state_id.country_id:
self.country_id = self.state_id.country_id
In odoo 13 *onchange_state* has been changed to *_onchange_state*.
Hope it helps,
Thanks

Hi,
The error message says that the function that you are trying to super is not existing inside the model. ie, the function onchange_state is not there inside odoo13 in this model.
In v13, the function might have changed or logic might have rewritten in some way, so you have to check and adjust code accordingly.

Thanks
