I cannot Exercise Tracker task#8 which : The response returned from POST /api/users/:_id/exercises will be the user object with the exercise fields added.
I tried a lot and all tasks I passed except this one.
my code is:
const express = require('express')
const app = express()
const cors = require('cors')
require('dotenv').config()
// mycode
let mongoose = require('mongoose')
mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true })
.then(() => console.log('MongoDB connected'))
.catch(err => console.log(err));
// until here
app.use(cors())
app.use(express.static('public'))
app.use(express.json())
app.use(express.urlencoded({ extended: true })) // mycode
app.get('/', (req, res) => {
res.sendFile(__dirname + '/views/index.html')
});
// my code
const { Schema } = mongoose;
const userSchema = new Schema({
username: { type: String, required: true, unique: true },
count: { type: Number, default: 0 },
log: [{
description: { type: String, required: true },
duration: { type: Number, required: true },
date: { type: Date, required: false }
}]
});
const User = mongoose.model('User', userSchema);
// username
app.post('/api/users', async (req, res) => {
const { username } = req.body;
if (!username) {
return res.status(400).json({ error: 'Username is required' })
}
try {
const user = new User({ username });
const savedUser = await user.save();
res.json({
username: savedUser.username,
_id: savedUser._id
});
} catch (err) {
console.log(err);
res.status(500).json({ error: 'Server error' })
}
})
app.get('/api/users', async (req, res) => {
try {

res.json(users.map((user) => ({

if (err.name === 'ValidationError') {
res.status(400).json({ error: err.message });
} else {

}
}
})
// logs
