代码是这样的
public AddScanRecordResult addScanRecord(AddScanParmsDTO parms) {
AddScanRecordResult result = new AddScanRecordResult();
FBAReceiveScan fBAReceiveScan = new FBAReceiveScan();
//报错的是下面这一行
FBAReceiveBasket existingProduct = fBAReceiveBasketRepository.getBasketByProductId(parms.getResult().getProduct().getId(), parms.getCode());
final FBAReceiveBasket fbaReceiveBasket = existingProduct == null ? new FBAReceiveBasket() : existingProduct;
// set scan record
fBAReceiveScan.setProduct(parms.getResult().getProduct());
fBAReceiveScan.setFnsku(parms.getResult().getScanned());
fBAReceiveScan.setQuantity(parms.getFbaReceiveQTY());
fBAReceiveScan.setTracking(parms.getResult().getTracking());
fBAReceiveScan.setCode(parms.getCode());
报错是这样的，只要第一次查询库里没有这个product 就会报错，第二次就正常了，如何解决呢
