Neo4jPHP交易错误

Question

我正在使用最新版本的jadell的Neo4JPHP库和Neo4j版本2.当我尝试提交2个不同的cypher查询时，它会给我一个InvalidFormat错误。代码是：

    $transaction = $this->client->beginTransaction();
    $queryA = new Everyman\Neo4j\Cypher\Query($this->client, "start n=node(485183) return id(n) as neoid, n.mongoid as mongoid");
    $queryB = new Everyman\Neo4j\Cypher\Query($this->client, "start n=node(485182) return id(n) as neoid, n.mongoid as mongoid");
    try{
        $results = $transaction->addStatements(array($queryA, $queryB), true);
    }
    catch( Exception $e){
        echo "<pre>";
        print_r( $e->getMessage());
        die;
    }

    return $results;

它给出了一个例外并打印出来：
