After attempting to add an extension, why does NodeJS continue to display CORS errors?

edit

NodeJS continues to display CORS errors even after attempting to add an extension because the extension may not have been properly installed or configured. It is also possible that the extension is not compatible with the version of NodeJS being used. Additionally, there may be other factors affecting the CORS error, such as incorrect server-side configurations or client-side scripting errors. Troubleshooting the issue may require further analysis of the code and configuration settings.
