After investigation, it was found that the transactionServiceGroup at line 84 of NacosRegistryServiceImpl is null, which should be corrected for line 195
removeOfflineAddressesIfNecessary(transactionServiceGroup, clusterName, newAddressList);
Change to：
if (StringUtils.isNotEmpty(transactionServiceGroup)) { removeOfflineAddressesIfNecessary(transactionServiceGroup, clusterName, newAddressList); }

@ChinaJeckXu Why is transactionServiceGroup null? Is the configuration missing?
But anyway, here is the need for a non-empty judgment, welcome to fix.
