RuntimeException is thrown when calling getOrCreateNode in batch mode #51

The following code segment works fine if calling from RestAPI directly.

RestNode userNode = restApi.getOrCreateNode(restApi.index().forNodes("user-id"),
                "user-id", userId, null);
        if (userNode != null){
            logger.debug("user node " + userNode.getId() + " is created.");
        }

However if running in a batch mode, I got RuntimeException:

public BatchRestResult recordBatch(RestAPI restApi) {
        BatchRestResult result = new BatchRestResult();
        RestNode userNode = restApi.getOrCreateNode(restApi.index().forNodes("user-id"),
            "user-id", user.getUserId(), null);
