Parse platform 解析JavaScript SDK查询不工作

我想知道您为什么会出现此错误：

错误代码：102，错误消息：$in需要一个数组

我正在使用Parse JavaScript SDK

它的数据结构如下所示：

Parse.Cloud.define(
    "unfollow",
    function(request, response) {
        var currentUserID = request.params.currentuser;

        var followedUserID = new Array(request.params.followeduser);

        var queryRemoveFollower = new Parse.Query("userRelation");
        queryRemoveFollower.containedIn("userObjectId", followedUserID);

        queryRemoveFollower.find({
            success: function(result) {
                for(var i=0; i<result.length; i++) {
                    result[i].remove("followers", currentUserID);
                    result[i].save();
                }

                var stopFollowingQuery = new Parse.Query("userRelation");
                stopFollowingQuery.equalTo("userObjectId", currentUserID);

                stopFollowingQuery.find({
                    success: function(result) {
                        for(var i=0; i<result.length; i++) {
                            result[i].remove("following", followedUserID);
                            result[i].save();
                        }

                        response.success("Unfollow succesful!");
                    },
                    error: function(error) {
                        response.success("Something went wrong. Error code: " + error.code + ", error message: " + error.message);
                    }
                });
            },
            error: function(error) {
                response.success("Something went wrong. Error code: " + error.code + ", error message: " + error.message);
            }
        });
    }
);

该函数的源代码如下：

Parse.Cloud.define(
    "unfollow",
    function(request, response) {
        var currentUserID = request.params.currentuser;

        var followedUserID = new Array(request.params.followeduser);

        var queryRemoveFollower = new Parse.Query("userRelation");
        queryRemoveFollower.containedIn("userObjectId", followedUserID);

        queryRemoveFollower.find({
            success: function(result) {
                for(var i=0; i<result.length; i++) {
                    result[i].remove("followers", currentUserID);
                    result[i].save();
                }

                var stopFollowingQuery = new Parse.Query("userRelation");
                stopFollowingQuery.equalTo("userObjectId", currentUserID);

                stopFollowingQuery.find({
                    success: function(result) {
                        for(var i=0; i<result.length; i++) {
                            result[i].remove("following", followedUserID);
                            result[i].save();
                        }

                        response.success("Unfollow succesful!");
                    },
                    error: function(error) {
                        response.success("Something went wrong. Error code: " + error.code + ", error message: " + error.message);
                    }
                });
            },
            error: function(error) {
                response.success("Something went wrong. Error code: " + error.code + ", error message: " + error.message);
            }
        });
    }
);

Parse.Cloud.define(
“展开行动”，
功能（请求、响应）{
var currentUserID=request.params.currentuser；
var followedUserID=新数组（request.params.followeduser）；
var queryremoveplower=new Parse.Query（“userRelation”）；
queryRemoveFollower.containedIn（“userObjectId”，followedUserID）；
queryRemoveFollower.find({
成功：功能（结果）{
对于（var i=0；i代码中的问题是行：

var followedUserID = new Array(request.params.followeduser);

JavaScript的数组构造函数有两个可能的构造函数：

new Array(element0, element1, ..., elementN)
new Array(arrayLength)

由于request.params.followeduser是一个整数，folowedUserID被初始化为长度为request.params.followeduser的空数组

修复方法是使用以下任一项（未测试…）：

或（首选）：

var followedUserId = [request.params.followedUser];
