../data/rooms.json -> Status 404

Here is my code for the XMLHttp request:

var roomsJSON = new XMLHttpRequest();
roomsJSON.onreadystatechange = function() {
    if (roomsJSON.readyState === 4) {
        if (roomsJSON.status === 200) {
            const rooms = JSON.parse(roomsJSON.responseText);
            for (let room of rooms) { console.log(rooms) }
        } else {
roomsJSON.open('GET', "../data/rooms.json");

Console Output:

> GET http://port-80-5dezzhp748.treehouse-app.com/data/rooms.json 404 (Not Found)

> 404

> XHR finished loading: GET "http://port-80-5dezzhp748.treehouse-app.com/data/employees.json".

> XHR failed loading: GET "http://port-80-5dezzhp748.treehouse-app.com/data/rooms.json".

Hi Samuel 👋

I just had a look at the workspace but the rooms.json file should be present when opening the workspace for this video. If you still have a workspace open from the previous videos in this course you may want to try and close it to then launch the one connected to this video.

To avoid anyone else running into this issue in the future I've just updated the files from the previous workspaces to include that same rooms.json file 🙂

The code is looking for a file named "rooms.json" in the "data" directory, but there is no such file in workspace environment. Did one perhaps get deleted by mistake?

I'm not sure. I'm just following the instructions and forked the same workspace from this video:
