Bug fix
Description
If edge-runtime is behind a reverse proxy like Cloudflare, sudden socket closures (#641) will appear as 502 (Bad Gateway) on the surface.
Returning a 502 without any warning is confusing to users, so if respondWith throws an exception, we make sure to always expose the cause of the error by using
console.error.
