Timestamp Microservice /api/1451001600000 test not working

Tell us what’s happening:
I pass all the tests, except for 1. Any assistance would be appreciated.

// running tests A request to


should return

{ unix: 1451001600000, utc: "Fri, 25 Dec 2015 00:00:00 GMT" }

// tests completed

When I go to that page, I get what I would expect:

Welcome there,

Hint: Look at the return types…

Remember, programming is very specific.

This is the return from the template project

{“unix”:1451001600000,“utc”:“Fri, 25 Dec 2015 00:00:00 GMT”}

My code returns the exact same

Here is where I do the return.

app.get("/api/:date_string", (req, res) => {
let dateString = req.params.date_string;

if (/\d{5,}/.test(dateString)) {
let dateInt = parseInt(dateString);

res.json({ unix: dateString, utc: new Date(dateInt).toUTCString() });

} else {
let dateObject = new Date(dateString);

if (dateObject.toString() === "Invalid Date") {
  res.json({ error: "Invalid Date" });
} else {
  res.json({ unix: dateObject.valueOf(), utc: dateObject.toUTCString() });


Expected: unix: 1451001600000
Actual: unix: "1451001600000"

Thanks. That did the trick. I didn’t even notice the difference.
