> API rate limit exceeded for 106.51.68.199. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)

The GitHub APIs that you are using to list files are getting rate-limited in my case. If somebody else is also facing this issue, just use a VPN or something like Cloudflare Wrap to change your ip - this should fix the issue.

P.S If you are the main dev, giving an option to the visitor to sign in using Github or use a caching layer will be really helpful to make this accessible for the new user.
