I’m trying to create an opportunity using code.But somehow there is an error saying PX.Data.PXOuterException: 'Error: Inserting 'Opportunity Address' record raised at least one error. Please review the errors.'. I tried for hours to solve this issue. Some help would be appreciated. The error message also says that the CountryID cannot be empty. But its not empty.

        var graph = PXGraph.CreateInstance<OpportunityMaint>();
        var opp = new CROpportunity();
        var addrs = new CRAddress();
        var bAddrs = new CRBillingAddress();
        var sAddrs = new CRShippingAddress();

        addrs.CountryID = "US";
        bAddrs.CountryID = "US";
        sAddrs.CountryID = "US";

        bAddrs.OverrideAddress = true;
        sAddrs.OverrideAddress = true;

        var addr1 = graph.Opportunity_Address.Insert(addrs);

        var addr2 = graph.Billing_Address.Insert(bAddrs);

        var addr3 = graph.Shipping_Address.Insert(sAddrs);

        graph.Save.Press();

        opp = graph.Opportunity.Insert(opp);

        opp.Status = "N";
        opp.ClassID = "PRODUCT";
        opp.StageID = "L";
        opp.CloseDate = DateTime.Now.Date;
        opp.Subject = "This is the fake subject";

        opp.OpportunityAddressID = addr1.AddressID;
        opp.BillAddressID = addr2.AddressID;
        opp.ShipAddressID = addr3.AddressID;
       
        graph.Save.Press();
