Every time I try to close POS session I receive an this error:
An error has occurred when trying to close the session. You will be redirected to the back-end to manually close the session.
Looking at the odoo log file, I see a warning message asking to
define income account for product X.
As far as I searched the setting, there is no such option!
I have installed odoo 15 Community Edition on my VPS with no demo data.
Currently I have only POS, Inventory and Invoice modules installed.
