Cors Error While Saving Challenge

I got error while saving the last project.


The project was succeed, it said that everything was expected but when the project wasn’t saved, it was still marked as uncompleted project. Please help me. Thankyou!

do you mean that you pressed Submit here, and then went to check, and the project was not marked as completed?

The project was marked as complete after I Submit it. But when it went back to https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures-v8, it was not marked, so I couldn’t get the certificate

are you able to create a list of steps to reproduce this? if the dev team is unable to reproduce it is going to be hard to investigate

Okay, so I will add some condition where I just found out this morning

  1. I made the challenge
  2. Everytime I type Ctrl + S, it says “An error occured trying to save your code”. I just found out, if I had <script src="script.js"></script> in my HTML, it shows the saving error. But if didn’t have script tag, it can save the code. And you know that I cannot complete this project if I don’t include the script tag
  3. I couldn’t save, but I could “Run the tests” and it says that I completed my project (all the test cases value are expected)
  4. When I was about to claim my certificate, the project was marked uncompleted and the code was reverted to the last saved
  5. I checked again in console and found that there is CORS error while saving my code

Error message:

Console message:
