Describe your issue in detail here.
Hello, I finished the project for Markdown Previewer and link the code from github to sandbox.
Everything works fine before I add the bundle.js to external resources.
After I add this link to external resources: https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js
The application broke and shows errors as below,
there isnt really any specifically listed supported environments. codepen.io is the default one to use for fcc since it has very good support, but replit.com
would be a more similar environment to codesandbox.io if you prefer that
Not sure what happened with CodeSandbox, now it doesn’t even work with Helmet loading the script. It used to work with this npm package all it does is use Helmet to add the script. But it doesn’t seem to work on CodeSandbox anymore. I can see the script gets loaded on the page but the test widget doesn’t show.
Anyway, if you want something like CodeSandbox you can use StackBlitz with a Vite React starter template and add the script to the index HTML file.
