Just a heads up, the CORS Anywhere proxy is no longer supported as of January 1st of this year. I built this project a while ago and was revisiting it with 403 errors, did some digging and found some documentation.
cors-anywhere → GitHub - Rob--W/cors-anywhere: CORS Anywhere is a NodeJS reverse proxy which adds CORS headers to the proxied request.
cors-anywhere update / issues → PSA: Public demo server (cors-anywhere.herokuapp.com) will be very limited by January 2021, 31st · Issue #301 · Rob--W/cors-anywhere · GitHub
I’m still trying to figure out the workaround on this, when I do Ill update this comment
