更新配列は、エラー

Question

をキャスト投げる私は

、ドキュメント内の配列を更新必要がありますが、私は、キャストエラーを取得しています。

'$ addToSet'が文字列をObjectIdにキャストしようとすると、エラーが発生します。

文字列は、フロントエンドアプリケーションからの正しいObjectId表現です。

私はここで何が欠けていますか？

マイコード：

const mongoose = require('mongoose'); 
const ObjectId = mongoose.Types.ObjectId; 
var modelosSelecionados=[array containing selected itens] 

    modelosSelecionados.forEach(function (item){ 
        if (item.selected){ 
        ModeloAnamnese.findOneAndUpdate({_id: new ObjectId(item.modeloanamnese._id)},{perguntasAtivas:{'$addToSet':new ObjectId(req.params.id)}}, function (err, data){ 
         console.log(err); 
         if(err) { 
          return res.status(500).json({'error' : 'error in deleting address'}); 
         } 
         }); 
        } 
        else ModeloAnamnese.findOneAndUpdate({_id: new ObjectId(item.modeloanamnese._id)},{perguntasAtivas:{'$pull':new ObjectId(req.params.id)}}, function(err, data){ 
         console.log(err); 
         if(err) { 
          return res.status(500).json({'error' : 'error in deleting address'}); 
         } 
         }); 
       }); 

//スキーマ

const mongoose=require('mongoose'); 
const modelosAnamneseSchema = new mongoose.Schema({ 
    nome:{type:String, unique:true}, 
    utilizado_por:[{type:mongoose.Schema.Types.ObjectId, ref:'Profissional'}], 
    padrao:{type:Boolean}, 
    perguntasAtivas:[{type:mongoose.Schema.Types.ObjectId,ref:'Perguntadeanamnese'}], 
    created_at:{type:Date,default:Date.now}, 
    altered_at:{type:Date,default:Date.now} 
}); 

module.exports=mongoose.model('ModeloAnamnese', modelosAnamneseSchema,'modeloanamneses'); 

const mongoose=require('mongoose'); 
const tipoperguntaAnamneseSchema = new mongoose.Schema({ 
    nome:{type:String, unique:true}, 
    created_at:{type:Date,default:Date.now}, 
    altered_at:{type:Date,default:Date.now} 
}); 

module.exports=mongoose.model('TipoPerguntaAnamnese', tipoperguntaAnamneseSchema,'tiposperguntasanamnese');

正しい順序は次のとおりです。文書化hereとして

{ $addToSet : { perguntasAtivas : new ObjectId(req.params.id) } } 

：

{ $addToSet: { <field1>: <value1>, ... } }
