Minimal reproduction:

import * as http from "node:http";

const server = http.createServer((req, res) => {
  // BUG: For some reason `req.url` is always exactly one character
  if (!req.url?.includes("foo/bar")) {
    throw new Error("fail");
  }
  return res.end();
});

server.listen(async () => {
  const addr = server.address()! as any;
  const res = await fetch(`http://${addr.address}:${addr.port}/foo/bar`);
  await res.text();
});
