如何通过sails-orientdb适配器运行OrientDB功能？

带有签名的水线方法有一个扩展名 .runFunction('FunctionName', args...) 但我无法使用我的用例。

我的OrientDB函数通过它的id：

返回给定用户顶点的朋友

var db = orient.getGraph(); 

return db.command("sql", "select expand(unionall(outE('IsFriendsWith').inV(), inE('IsFriendsWith').outV())) from " + id);

我在UserController控制器中的操作调用了我的orientDB函数：

findFriends: function (req, res, next) {
    console.log(req.param('id'));
    User.runFunction('findFriends', '#' + req.param('id')).from('OUser').limit(20).one()
        .then(function (result) {
                res.json(result);
    });
}

我错过了什么吗？

console.log（req.param（＆＃39; id＆＃39;））返回33：288786

我在orientdb控制台中获得以下日志：

    Cannot serialize record: #-2:0{findFriends:[3]} v0 [ONetworkProtocolBinary]{db=database} Error on unmarshalling record #-2:0 (java.lang.ClassCastException: com.tinkerpop.blueprints.impls.orient.OrientVertex cannot be cast to com.orientechnologies.orient.core.record.ORecord)

错误告诉我结果需要转换为记录？

我在OrientDB工作室得到这个结果，ID为＃33：288786：

    [
    {
        "@type": "d",
        "@rid": "#33:288787",
        "@version": 16,
        "@class": "User",
        "gender": false,
        "mail": "1",
        "no": "1",
        "moto": "1",
        "rel": "1",
        "ori": "1",
        "pass": "1",
        "birthDate": null,
        "online": false,
        "name": "1",
        "in_IsFriendsWith": [
            "#23:4"
        ],
        "@fieldTypes": "in_IsFriendsWith=g,"
    }
]

我真的不知道该怎么做。我刚刚开始使用帆和水线。提前谢谢！
