死機(jī)：運(yùn)行時(shí)錯(cuò)誤：內(nèi)存地址無效或無指針取消引用當(dāng)我添加statusCOD, err := c.route.FindStatusCODByOrigin(ctx, req.Origin)            if err != nil {                if err != sql.ErrNoRows {                    ddlogger.Log(ctx, span, "Find status cod destination and cod origin", err)                    errChan <- err                    return                }            }            if statusCOD != nil {                IsCODOrigin = statusCOD.IsCODOrigin                IsCODDestination = statusCOD.IsCODDestination            }在這個(gè)功能中for i, v := range detailShipments {        var dtPackage repo.PackageBaseModel        go func(idx int, vShipment repo.ShipmentDetailBaseModel, dataShipmentNew repo.ShipmentCODCreateModel) {            defer wg1.Done()            randomID := commonString.RandomWithCustomCharList(c.config.ShipmentCODIDRandom, c.config.ShipmentIDCharlist)            shipmentID := fmt.Sprintf("%s%s", prefix, randomID)            dataShipmentNew.ShipmentBaseModel.ShipmentID = strings.ToUpper(shipmentID)            dataShipmentNew.ShipmentDetailBaseModel = vShipment            var commodityName string            sCategory, err := c.shipmentCategoryRepo.FindOneShipmentCategoryByID(ctx, vShipment.ShipmentCategoryID.Int64)            if err != err && err != sql.ErrNoRows {                ddlogger.Log(ctx, span, "shipmentService-CreateShipmentCOD "+shipmentID, " Failed shipmentCategoryRepo.FindOneShipmentCategoryByID", err)            } else {                if sCategory != nil {                    commodityName = sCategory.CommodityName.String                }            }
