importing yjs makes EdgeRuntime crash

[threepointone]

Bug Report

Current behavior

Consider the following code to be run inside EdgeRuntime

import * as Y from "yjs";

addEventListener("fetch", (event) => {
  console.log(Y);
  return event.respondWith(new Response("hello world"));
});

All it does is import the yjs library and log it.

Now, we have a separate script that actually bundles it and runs it:

import { EdgeRuntime } from "edge-runtime";
import * as esbuild from "esbuild";

// bundle the code in initialCode.js
const initialCode = esbuild.buildSync({
  entryPoints: ["./initialCode.js"],
  bundle: true,
  write: false,
  format: "esm",
  target: "es2019",
  // minify: true, // uncommenting this line "fixes" the issue
}).outputFiles[0].text;

const runtime = new EdgeRuntime({
  initialCode,
});

const response = await runtime.dispatchFetch("https://example.com");

await response.waitUntil();

This throws the following error:

evalmachine.<anonymous>:6991
            throw new TypeError("Failed to parse URL from " + input, { cause: err });
                  ^

}

The workaround for this is to enable minify:true when bundling, and that makes the code work as expected.

Now, I'm not certain whether this is a bug with yjs, esbuild, or edge-runtime, but I suspect it's edge-runtime, because importing yjs in node works fine, as well as when it's bundled with esbuild. It's only when trying to import it inside edge-runtime that the error pops up. The stack trace implies an error with the url, which doesn't seem right.

Expected behavior/code

The code doesn't crash.
