插入时，Mongoose嵌套子文档重复键错误

Question

您好我正在使用mongoosastic插件（elasticsearch.js的包装器）和mongoose.js。 简而言之，我有一个名为Event的模型，它具有声明为Game（模型名称）的子项（嵌套子文档）。更多Game将其他子项（嵌套子文档）声明为Result（模型名称）。所以，结果是游戏和游戏的孩子是事件的孩子。

所有这些属性都有一个名为nodeId的属性，该属性是唯一索引和必需的。 没有重复的nodeIds，我已经以编程方式检查了我的数据，所以我想知道我的模型声明是否有问题......

var ObjectSchema = new Schema({
    key: {
        unique: false,
        index: false,
        type: String,
        es_indexed: true
    },
    value: {

我在导入时遇到的错误如下：
