nhandledPromiseRejectionWarning: ValidationError: user validation failed: password: Path `password` is required - validationerror

Question

I'm trying to register users using node and mongo but I get this ValidationError:
unhandledPromiseRejectionWarning: ValidationError: user validation failed: password: Path password is required., username: Path username is required., email: Path email is required.
this is my signup function.
exports.signup = async function (request, res, next) {
try {
let user = await db.User.create(request.body);
console.log(user);
let { id,email,username } = user;
let token = jwt.sign({
id,
email,
username
},
process.env.SECRET_KEY
);
return res.status(200).json({
id,
username,
token
})
} catch (err) {
if (err.code === 11000) {
err.message = "sorry, username/email are token";
}
return next({
status: 400,
message: err.message
})
}
this is my user model
const userSchema = new mongoose.Schema({
email: {
type: String,
required: true,
unique: true,
},
username: {
type: String,
required: true,
unique: true
},
password: {
type: String,
required: true,
},
profileImageUrl: {
type: String,
},
messages:[{
type:mongoose.Schema.Types.ObjectId,
ref:'Message'
}]
})
userSchema.pre('save', async function (next) {
try {
if (!this.isModified('password')) {
return next();
}
let hashedPassword = await bcrypt.hash(this.password, 10);
this.password = hashedPassword;
return next();
} catch (err) {
return next(err);
}
});
const User = mongoose.model("user", userSchema);
module.exports = User;
NOTE: I'm using Postman to test this.

Answer 1

So yeah I found the problem. the fields are required so if you try to insert a new user with empty fields you get that error. The fields were empty because The 'body-parser' middleware only handles JSON and urlencoded data, not multipart. So I had to change my index file to
app.use(bodyParser.urlencoded({
extended: true
}));
I also changed the content type in Postman to "X-www-form-urlencoded". Now the request body is populated and the user is inserted correctly

Answer 2

I also faced this error.
In your user model remove required:true in all fields like this:
email: {
type: String,
unique: true
}
