為什么MongoDB檔案在執行控制臺日志時隱藏了其大部分屬性？-有解無憂

我有一個 MongoDB 檔案，我可以通過這樣做來訪問一個檔案：

let profileData;
try {
    profileData = await profileModel.findOne({ userID: message.author.id });
    if (!profileData) {
        let profile = await profileModel.create(aBlueprintObject);
        profile.save();
    }
} catch (err) {

}

（不要介意是什么message。只要知道這profileData是集合中的一個檔案profileModel，并且aBlueprintObject是我用來創建檔案的默認物件。）

現在，當我這樣做時console.log(profileData)，它會回傳：

{
  _id: new ObjectId("615023dd2d00db6f8bef1ea9"),
  userID: '801715615424315432',
  username: 'Tyrcnex#9403',
  items: [],
  bank: 0,
  coins: 1610
}

但是當我運行這段代碼時：

for (const item in profileData) {
    console.log(profileData[item]);
}

它回傳這個怪物：

InternalCache {
  activePaths: StateMachine {
    paths: {
      coins: 'init',
      bank: 'init',
      username: 'init',
      items: 'init',

      userID: 'init'
    },

這兩個人不應該做同樣的事情嗎？這跟這有關系Prototype嗎？

我想要做的就是將檔案與物件進行比較：如果檔案有物件沒有的東西，代碼將洗掉檔案中的該屬性。但是現在我找不到遍歷檔案的每個專案的方法，有什么想法嗎？
