Javascript Node.js错误：RangeError:超出最大调用堆栈大小

我是NodeJs的新手，在运行我的应用程序时遇到了一个问题。我正在尝试制作一个图片竞赛页面，我想在主页上显示最新的评论，并将评论发布的图片附在上面。我得到的错误如下所示：

RangeError:超出了最大调用堆栈大小

，在模型中引用了我的代码

。（\rootproject\models\comment.js:15:16）

整个错误代码如下所示：

提前谢谢你

您在

async.each

中做什么？我正在使用

async.each

循环查看

注释

集合中的每个项目，并将每个项目作为参数发送到回调函数

attachImage

。第三个参数应该是整个系列完成后执行的回调函数集合。看起来像是您的

Comment

schema有一个调用自身的模式（可能是通过另一个模式间接调用的）。我的注释模型看起来像这样：

var CommentSchema=newschema（{image\u id:{type:ObjectId}，email:{type:String}，name:{type:String}，gravatar:{type:String}，注释：{type:String}，时间戳：{type:Date，“default”：Date.now}）；CommentSchema.virtual（'image'）.set（函数（image）{this.image=image；}）.get（函数（）{returnthis.\u image；}）
var models = require('../models'),
async = require('async');

module.exports = {
newest: function(callback) {
    models.Comment.find({}, {}, {
            limit: 5,
            sort: {
                'timestamp': -1
            }
        },
        function(err, comments) {
            var attachImage = function(comment, next) {
                models.Image.findOne({
                        _id: comment.image_id
                    },
                    function(err, image) {
                        if (err) throw err;

                        comment.image = image;
                        next(err);
                    });
            };

            async.each(comments, attachImage,
                function(err) {
                    if (err) throw err;
                    callback(err, comments);
                });
        });

}
};
