@aegisdaemon you also seem to use nodejs' fs module which is not available on workers

you could store it in cloudflare's r2 (or any other cdn/storage) and fetch it or you import it directly and bundle it with your code i'd suggest reading https://developers.cloudflare.com/workers/wrangler/bundling
