My 'Timestamp Microservice' project is failing the test 'Your project can handle dates that can be successfully parsed by new Date(date_string)'

Hello. Hope that you all are doing good

My ‘Timestamp Microservice’ project is failing the test ‘Your project can handle dates that can be successfully parsed by new Date(date_string)’

I have tested the API with these methods of creating Date objects at MDN docs

let today = new Date()
let birthday = new Date('December 17, 1995 03:24:00')
let birthday = new Date('1995-12-17T03:24:00')
let birthday = new Date(1995, 11, 17)            // the month is 0-indexed
let birthday = new Date(1995, 11, 17, 3, 24, 0)
let birthday = new Date(628021800000)            // passing epoch timestamp

Please help me find what I am missing.

Here is my code

// server.js
// where your node app starts

// init project
var express = require("express");
var app = express();

// enable CORS (
// so that your API is remotely testable by FCC
var cors = require("cors");
app.use(cors({ optionsSuccessStatus: 200 })); // some legacy browsers choke on 204


app.get("/", function (req, res) {
  res.sendFile(__dirname + "/views/index.html");

// Here is the beginning of my own code ======================================

// function to return the required object if the argument is a valid date object
function returnRequiredObject(dateObject) {
  return {
    unix: new Date(dateObject).getTime(),
    utc: new Date(dateObject).toUTCString(),
// function to test if the passed argument is a valid date object
function isArgumentValidDateObject(argument) {
  return !isNaN(argument.getTime());

// Handler if no date is sent
app.get("/api/", (req, res) => {
  const date = new Date();
    unix: new Date(date).getTime(),
    utc: new Date(date).toUTCString(),

// Handler for all the dates submited
app.get("/api/:date", (req, res) => {
  const dateArgument =;
  // if dateArgument is valid as a string
  if (isArgumentValidDateObject(new Date(dateArgument))) {
    return res.send(returnRequiredObject(new Date(dateArgument)));
  // if dateArgument is valid as an Int
  if (isArgumentValidDateObject(new Date(parseInt(dateArgument)))) {
    return res.send(returnRequiredObject(new Date(parseInt(dateArgument))));
  return res.send({ error: "Invalid Date" });
// Here is the end of my own code ============================================

// listen for requests :)
var listener = app.listen(process.env.PORT || 5005, function () {
  console.log("Your app is listening on port " + listener.address().port);

Not sure if you fixed it but when I tested your code it passed.

As an aside, I’m not sure if timezones can affect this challenge. When I compare the dates I get in the browser using the console vs my response from repl they are different.

Thank you for the time.
The test is still not passing for me.

I also just completed the 'Request Header Parser Microservice project and it is passing all the tests. I am not sure how to know if I passed because I can’t see the blue tick

Can you link to your repl please.

I works!
Thank you for the help. I cloned the repo and was working from my local machine. When I used repl, everything worked fine for both projects

Was it only accessible locally or did you serve it using a publicly available server?

Anyway, good job passing the challenges.

It was only available on localhost.

Thank you
