更新并返回新文档mongodb angularjs 2打字稿

Question

我将returnNewDocument修复为true，但仍然有旧文档，我该如何解决这个问题？

public updateBestScore(scoreBD: ScoreBD, level: string): Promise<any> { 
     return client.connect(url) 
      .then(
      // Promesse tenue 
      (db: any) => db.collection('BEST_SCORES').findOneAndUpdate(
       { "level": level.toLowerCase, "bestScore.username": scoreBD.usernameBD }, 
       { $set: { "bestScore.$.score": scoreBD.score, "bestScore.$.username": scoreBD.usernamePlayer} }, 
       { returnNewDocument : true } 
      ) 
       .then(
       (res: any) => { 
        db.close(); 
        console.log("resultat : ", res); 
        if (res.lastErrorObject.updatedExisting === true) { 
         console.log("resultat apres findOneAndUpdate : ", res.value.bestScore); 
        } 
       }), 
      // Promesse rompue 
      (err: any) => { throw "erreur"; }); 

    }

我想更新我的集合并返回新的更新集合。但该方法仍旧会在更新前返回旧集合
