Server Error

I am getting 500 Internal Server Error.
My site is a single static .html file hosted with Netlify, so I’m struggling to understand how it has a server error.

You’ve requested a page on a website that is on the Cloudflare network. An unknown error occurred while rendering the page.

If you are the owner of this website you should login to Cloudflare and check the error logs

My workers code was not doing anything complicated and does not show any errors in the console.
