我嘗試將我的登錄頁面與 mongoose 連接起來。不幸的是，它不起作用。我收到錯誤：
ObjectParameterError: Parameter "filter" to findOne() must be an object, got 637798b57bfa9d5fbede9c30
我整天都在努力尋找解決方案，但我t figure it out. I仍然可以學習編碼并努力理解它的一切，但我大部分都理解。

我認為問題出在這里的某個地方：
passport.use(new LocalStrategy({ usernameField: 'email' }, authenticateUser))
passport.serializeUser((User, done) => done(null, User._id))
passport.deserializeUser(function(_id, done) {
User.findOne(_id, function (err, User) {
done(err, User);
});
});
但我不確定...
非常感謝您的幫助。
uj5u.com熱心網友回復：
您正在混合使用findOne和findById
findById不需要物件，但_id. 正如檔案（以及方法名稱）所解釋的那樣，在它通過 id 找到的鉤子下，就像這樣做一樣findOne({_id: id})。
從檔案：
findById(id)幾乎*等同于findOne({ _id: id })
所以問題是你試圖簡單地使用_idwhen 方法期望一個物件與過濾器匹配。
所以你可以使用User.findOne({_id: _id})或User.findById(_id)
