Demo

Here's an example error message:

$ ./target/debug/deno eval 'await fetch("http://localhost:4444")'
error: Uncaught (in promise) TypeError: error sending request from 127.0.0.1:55985 for http://localhost:4444/ (127.0.0.1:4444): client error (SendRequest): connection closed before message completed
await fetch("http://localhost:4444")
