Model has no attribute "get_warehouse"
Since 6efb525a7b23, function field warehouse on sale line has method "on_change_with_warehous" instead of "get_warehouse". But method "get_warehouse" was called in module account_tax_rule_country: https://foss.heptapod.net/tryton/tryton/-/blob/0a0a644d5a20e6f838c30a7ef7f3d4c550422142/modules/account_tax_rule_country/sale.py#L33
