"Error: Illegal arguments: string, undefined" and stop server in node JS
Solution 1
In the name of the universe programmer
in my case i forgot to select the password because in database the password was ((select: false))
this code for app
const user = await User.findOne({email}).select("+password")
i forgot to append the ((.select("+password")))to the findOne
and I received this error ; Error: Illegal arguments: string, undefined
and this code for database
const User = new mongoose.Schema({
username:{
type:String,
required: [true,"نام کاربری ضروری است"]
},
email:{
type:String,
required: [true,"رایانامه ضروری است"],
unique: true,
match:[
/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{1,3})$/,
"لطفا یک رایانامه صحیح وارد کنید"
]
},
password:{
type:String,
required:[true,"رمز ضروری است"],
minlegth: 5,
select: false
}
})

I found the problem in here. it is not things regarding the code.
The thing is i had registered two users with same user name and different password. then when i tried to login with the user name and one password it occurred this error and stop the server.
Because there is embarrassing situation with find password to username that user entered. because there are two password with same username.
Solution 3
In my case, I was using arrow function
userSchema.methods.comparePassword = async (enterdPassword) => {
return await bcrypt.compare(enterdPassword, this.password);
};
which I converted to normal function
userSchema.methods.comparePassword = async function (enterdPassword) {
return await bcrypt.compare(enterdPassword, this.password);
};
that solved the problem

I'm trying to build logging application in node JS. in here password authentication app do not work properly. when i enter username and password it occur following error and stop server.
this is the error.
Here is the code for authentication part
passport.use(new LocalStrategy( function(username, password, done) { User.getUserByUsername(username, function(err, user){ if(err) throw err; if (!user) { return done(null, false, {message: 'Unknown user'}); } User.comparePassword(password, user.password, function(err, isMatch){ if(err) throw err; if (isMatch) { return done(null, user); } else { return done(null, false, {message: 'Invalid password'}); } }); }); }));
This code work for Unknown user. but it is not working for comparing username and password. i cannot see any bug in here. i want a help for solve this.
