Learn ReactJS Code Editor returning 404 error


Build a Stateful Component Class - Learn ReactJS: Part II, section 1

The Code Editor itself is not showing up, it seems to be failing on the server side from Codecademy itself, has anyone else seen this?

The chrome developer console error is:


Failed to load resource: the server responded with a status of 404 (Not Found)

Editor Issue

it happens to me aswell, waiting for an answer from somebody


Definitely some server side issues - possibly load or a flooded pool instance on the editor server.

It would seem that ReactJS is having the same problem Java is having today where the code editor is not accesible, no one can type in the code editor, and past code is shown as correct or passed but the code does not show up. You can read about the different issues in Java here: https://discuss.codecademy.com/t/java-lessons-suspended/70811/7 and here: https://discuss.codecademy.com/t/java-intro-lesson-1-no-code-in-code-editor-box-cant-complete/70835

I would suggest filling out a bug report to codecademy and just waiting to see what happens! For right now maybe try another language?



I saw those other issues when searching this morning and filed a bug on the React portion as well, just wanted to provide the details above. I'm a software architect for my current company and am just trying to get a quick ramp up on React right now for a project - so I don't need anything outside of React - I'm moving over to the Facebook/GitHub direct tutorials - I liked this format better but life intervenes :).

Thanks again for the response.

Can't access the code editor

Hey all, we are indeed experiencing some server problems related to the work terminal (as was well diagnosed by some intrepid users). Our engineers are aware of the problem and are working on fixing it - hopefully there shouldn't be too much downtime.

Can't access the code editor

I'm in lesson 'this.props' on ReactJS Part 1 exercise 7, and it says in the instructions to select 'talker.js' file- that I can't see.. All I see is an icon of a folder but it seems locked..
Is this a common bug? What do I do?
Thanks :slight_smile:


This should be fine for most users now, though smaller issues may still arise occasionally until we have a deeper fix in place. Keep us posted!
