Exercise Tracker Project - Stuck on last test (" Test timed out error" )


My code gives me the correct output for the last " from , to ,limit" test which I separately verified with “https://exercise-tracker.freecodecamp.rocks/ " however, for some reason it keeps failing with " Test timed out error” when freeCodeCamp runs its last test.

My only issue is with this last test bit:

" You can add from , to and limit parameters to a GET /api/users/:_id/logs request to retrieve part of the log of any user. from and to are dates in yyyy-mm-dd format. limit is an integer of how many logs to send back."

I’m new to coding and would appreciated greatly if somebody can point out where the error is. This has been bugging me for days now.

Please find below my code as typed in Replit: ( You can scroll to the GET logs section where I believe the issue may lie if any.)

const express = require('express')
const app = express()
const cors = require('cors')
const bodyParser = require('body-parser')
const mongoose = require("mongoose");
const { Schema } = require("mongoose");

const exercise = {
  description: { type: String, required: true },
  duration: { type: Number, required: true },
  date: { type: String, required: true }

const personSchema = new Schema({
  username: {
    type: String,
    required: true
  count: Number,
  exercise: {
    type: Array,
    value: exercise

const Person = mongoose.model('Person', personSchema);
const URL = process.env.MONGO_URI;

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

app.use(bodyParser.urlencoded({ extended: false }));

   .post((req, res) => {
    let a = req.body.username;
    let person = new Person({ username: a, count: 0 });
    person.save(function(err, data) {
      res.json({ "username": data.username, "_id": data._id });

   .get((req, res) => {
    Person.find((err, data) =>


app.post('/api/users/:_id/exercises', (req, res) => {

  Person.findById(req.params._id, (err, data) => {
  let datt = '';
    // console.log(req.body.date, typeof req.body.date)
   if (typeof req.body.date == 'undefined' ||
      typeof req.body.date == '') {
      datt = (new Date()).toDateString();
    else {
      datt = (new Date(req.body.date)).toDateString();}

   exercise.description = req.body.description;
   exercise.duration = parseInt(req.body.duration);
   exercise.date = datt;
   data.count = data.count + 1;

      "_id": req.params._id,
      "username": data.username,
      'date': exercise.date,
      'duration': exercise.duration,
      'description': exercise.description

   } );  });   });

     app.get('/api/users/:_id/logs', (req, res) => {

          //console.log(req.params, req.query, req.path);

           Person.findById(req.params._id, (err, data) => {
                    // console.log(data)
                    let limit = data.exercise.length;
                    let from = '1970-01-01';
                    let to = '2038-01-18';

                   if (typeof req.query.from != 'undefined')
                  {from = req.query.from;
                   if (typeof req.query.to != 'undefined')
                  { to = req.query.to;
                  if (typeof req.query.limit != 'undefined')
                  { limit = parseInt(req.query.limit);

                  let fromF = new Date(from).toDateString();
                  let toF = new Date(to).toDateString();

                  let ans = data.exercise.filter(       q =>
                          new Date(q.date).getTime() >= new Date(from).getTime() &&
                          new Date(q.date).getTime() < new Date(to).getTime()

                 let resp = {
                           "_id"               : req.params._id,
                        "username": data.username

                   if (from != '1970-01-01') resp.from = fromF;
                   if (to != '2038-01-18') resp.to = toF;

                 resp.count= ans.slice(0, limit).length;
                 resp.log = ans.slice(0, limit);


         if (typeof req.query.from != 'undefined' ||
                     typeof req.query.to != 'undefined'|| 
                    typeof req.query.limit != 'undefined')
                            console.log(resp);  }          });    });

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

I have tried using a different system with higher internet speeds but it did not make any difference.

After hours of struggling, I have finally set up my local server and ran the code locally on Visual Studio Code which has given very strange results.
Sometimes all the tests pass.
It just appears to randomly pass and fail tests - especially the logs related tests.

I have tried clearing my Mongo Database, which occasionally results in all the tests passing.

Please post a link to your Replit.

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).


The problem seems to be with Replit servers.

After exporting data to Github and running it via Gitpod, all tests have passed.
I believe the issue is because the project’s verification script has a timeout set a bit low
causing random test bits to fail with Time Out Error during I guess heavy server traffic.


After completing more projects , the real issue I observe is Replit server connection with MongoDB. Projects involving some database related functions like adding, reading, deleting , updating values tend to fail freecodecamp server functional tests with timeout error. The easy way to circumvent this problem I found out is to use Glitch for the projects requiring DB functionality . (Free account 1000hrs / month). Give it a try !!
