`[ERR_INVALID_URL]: Invalid URL: [object Object]` on object based passthrough requests

When doing a http request with the node.js http client with an object like:

{
    hostname: "localhost",
    path: "/",
    origin: "http://localhost:3728",
    port: 3728,
    method: "GET",
}

the error in the subject is thrown.

For some reason it does not like the origin key. If it is removed the this works as expected.

So fix is easy in in userland. In theory. Unfortunately I'm using @elastic/elasticsearch which is creating requests like this internally in some situations and I have no control over it.

Here's a jest test reproducing the error

import http from "http";
import { setupServer } from "msw/node";

test("can make raw passthrough request with an object", async () => {
    const mockServer = setupServer(); // No interceptors!
    mockServer.listen();

    // Real server handling the pass through
    const server = http.createServer((req, res) => {
        res.writeHead(200, { "Content-Type": "text/plain" });
        res.end("Hello from real server");
    });

    await new Promise<void>((resolve) => {
        server.listen(3728, () => {
            resolve();
        });
    });

    const doGet = async () => {
        return await new Promise<http.IncomingMessage>((resolve, reject) => {
            http.request(
                {
                    hostname: "localhost",
                    path: "/",
                    origin: "http://localhost:3728",
                    port: 3728,
                    method: "GET",
                },
                resolve,
            )
                .on("error", reject)
                .end();
        });
    };

    let res;

    try {
        res = await doGet();
    } finally {
        server.close();
    }

    expect(res.statusCode).toEqual(200);
});

This crashes with

TypeError: Invalid URL: [object Object]TypeError [ERR_INVALID_URL]: Invalid URL: [object Object]

From debugging the source via node_modules the error seems to origin from the request.url.toString() call here:
