Expected behavior:

Order Canceled

Comment:

Error exist in line:

 price_unit = self.env['account.tax']._fix_tax_included_price_company(seller.price, procurement.purchase_line_id.product_id.supplier_taxes_id, procurement.purchase_line_id.taxes_id, self.company_id) if seller else 0.0

the problem is with value: self.company_id

should be: procurement.company_id





suppliers = procurement.product_id.seller_ids\
