Use the .env File - Issue [RESOLVED]

[FIXED]: A fix has been pushed onto the fcc-bground-package, and this should no longer be a problem. If you started this project recently, you will likely need to:

  • Open the terminal/shell
  • Run the command npm update --save
  • Restart the app

As of <04/02/2021, a change has caused the above mentioned lesson to be uncompletable. Some have also been unable to complete:

  • Implement a Root-Level Request Logger Middleware
  • Chain Middleware to Create a Time Server

If you encounter this, the best course of action is to skip the lesson, and continue with the curriculum.

As nothing obvious has changed on freeCodeCamp’s side, this is likely an issue on Repl.it’s side.

Current Debugged Steps
  1. Tested code which previously used to pass - no longer passes
  2. Downgraded express package - no effect
  3. One user was able to pass, and the noticeable difference was their origin was not freecodecamp.org, when they submitted.
  4. All manor of sending data via stringifying etc.

I’ve seen that error before, in other projects, when I try to .json a response that is actually a 404 (and sent back a custom HTML 404 page).

Let report this on our tracker too. Do we have full steps to reproduce? I understand its intermittent.

I have opened an issue on GitHub.

Steps to reproduce are:

  1. Go to challenge mentioned
  2. Add code required to pass
  3. Submit code
  4. App throws error, and crashes, and does not pass tests.

I was able to reproduce every time. A Camper I was pair-programming with could not reproduce it at all, and I noticed their difference was, when they submitted, their origin was from some .repl domain, whilst the expected origin should be freecodecamp.org

I have had the same error. It works fine until I submit it on freecodecamp. It then throws above error.

A post was split to a new topic: Install and Set up Mongoose Express Error

LOL and there I was trying the impossible to pass this challenge. Thanks for the info.

Is the error caused by it somehow interpreting HTML as JSON? I wonder if we, the users, can’t write some code to get around it. If we can’t, then hopefully this gets fixed upstream soon.

Once it’s fixed, email us please (just in case we don’t have this page opened up and miss the notification). Mine is REDACTED . Thanks.
