bug(curriculum): Advanced Node Challenges fail when using localhost for url

Not sure if this will actually be a bug once we go to production, but I noticed if I use http://localhost:3001 (my local running version of the first challenge in the Advanced Node Challenges, none of the tests pass and there are several errors in the console. This also happens when I run everything locally.

Using the same url on the current production site for the same challenge does not fail any of the tests.

I have validated the solution is correct.

This is annoying if you are trying to make changes to a challenge to validate the tests are working as they should (without having to run npm run:test:curriculum) after every code change while working on challenge tests.

Don’t be so hard on yourself @raisedadead. It is as @RandellDawson guessed. The CORS in the boilerplate is where the error is coming from.

Currently the boilerplate only excepts requests from *.freecodecamp.org domains, hence the CORS error when on .dev or running the learn platform locally.

In short, not a blocker for the next release.

For developing the challenges locally, update the cors in the boilerplate to accept /https?:\/\/localhost(:\d*)?/

@raisedadead Should we close this?
