Exercise-tracker: Log help

[sip]

Hello,

In the last tasks of the exercise-tracker assignment we have to utilise “/log” to find the history of activity for specific users. It’s been almost a month and I am still struggling. My code returns exactly what I want it to return and meets all the requirements of the exercise but the automatic checker of freecode camp still marks me as wrong for the last 5 questions (oddly enough not the very last one). Can someone help me spot the problem? and if possible potentially reccommend a solution as well.

Here is the code:

const express = require('express')
const app = express()
const cors = require('cors')
const mongoose = require("mongoose")
const {Schema} =  mongoose;
const bodyParser = require("body-parser")
require('dotenv').config()
app.use(cors())
app.use(express.static('public'))
app.use(bodyParser.urlencoded({ extended: false}));
app.use(bodyParser.json())


const MONGO_URI = process.env.MONGO_URI;
mongoose.connect(MONGO_URI)


const personSchema = new Schema({
  "username": { type: String, required: true}
})

const exerciseSchema = new Schema({
  "userId": {type: String, required:true},
  "description": {type: String, required: true},
  "duration": {type: Number, required: true},
  "date": {type: Date, required: true},
})

const Person = mongoose.model("Person", personSchema)

const Exercises = mongoose.model("Exercises", exerciseSchema)


app.get('/', (req, res) => {
  res.sendFile(__dirname + '/views/index.html')
});




app.post("/api/users", (req, res) =>{
  const username = req.body.username
  const createPerson = new Person({ "username": username})
  createPerson.save((error, data) =>{
    if(error){
      res.json(error)
    } else{
      res.json(data)
    }
  })
})

app.get("/api/users", (req, res) =>{
  Person.find({}, (error, data)=>{
    if(error){
      res.json(error)
    } else{
      res.json(data)
    }
  })
})


app.post("/api/users/:_id/exercises", (req, res) => {
  const id = req.params._id
  const {description, duration, date} = req.body
  Person.findById(id, (error, usrData) => {
    if(error) {
      res.json(error);
    }else{
      const newExercises = new Exercises({
        userId: id, 
        description,
        duration,
        date: new Date(date), 
      })
      newExercises.save((error, data) => {
        if(error) {
          res.json(error)
        }else {
          const { description, duration, date, _id} = data;
          res.json({
            username: usrData.username,
            description,
            duration,
            date: date.toDateString(),
            _id: usrData.id
          })
        }
      })
    }
  })
})

app.get("/api/users", (req, res) =>{
  Person.find({}, (error, data)=>{
    if(error){
      res.json(error)
    } else{
      res.json(data)
    }
  })
})


app.get("/api/users/:_id/logs", (req, res) => {
  const { from, to, limit } = req.query;
  const id = req.params._id;
  let dateObj = {}
  let usrFilter = {"userId": id}
  let limitReach = limit ?? 500
  Person.findById(id, (error, usrData) => {
    if(error) {
      res.json(error);
    }else{
      if(from){
        dateObj["$gte"] = new Date(from)
      }
      if(to){
        dateObj["$lte"] = new Date(to)
      }
      if(from || to ){
        usrFilter.date = dateObj
      }
      if(null){
        newDate =  new Date()
      }
      Exercises.find(usrFilter).limit(+limitReach).exec((error, info) => {
        if(error){
          res.json(error)
        }else{
          const count = info.length
          const {username, _id} = usrData;
          const log = info.map((l) => ({
            description:l.description,
            duration:l.duration,
            date:l.date.toDateString()
          }))
          res.json({username, count, _id, log})
        }
      })
    } 
  })
})

app.get("/mongo-health", (req, res) =>{
  res.json({status: mongoose.connection.readyState})
})


const listener = app.listen(process.env.PORT || 3000, () => {
  console.log('Your app is listening on port ' + listener.address().port)
})

It doesn’t appear that your are handling optional dates. Go through all your routes and log the route name and route inputs at the beginning of each route and then log all the route responses (everywhere you have res.json(...) or whatever) to see what your routes are doing.

Post a REPL for better debugging.
