Inertia SSR + React - `ReferenceError: route is not defined` only on some pages

Well after some messing around, I was able to get this to work, after running bun install ziggy-js and using this as my ssr.jsx file and HandlesInertiaRequests.php file:

import { createInertiaApp } from "@inertiajs/react";
import createServer from "@inertiajs/react/server";
import ReactDOMServer from "react-dom/server";
import { route } from "ziggy-js";

const appName = import.meta.env.VITE_APP_NAME || "Laravel";

createServer((page) => {
    globalThis.Ziggy = page.props.ziggy;

    return createInertiaApp({
        title: (title) => `${title} - ${appName}`,
        page,
        render: ReactDOMServer.renderToString,
        resolve: (name) => {
            const pages = import.meta.glob("./Pages/**/*.jsx", { eager: true });
            return pages[`./Pages/${name}.jsx`];
        },
        setup: ({ App, props }) => {
            const Ziggy = {
                // Pull the Ziggy config off of the props.
                ...props.initialPage.props.ziggy,
                // Build the location, since there is
                // no window.location in Node.
                location: new URL(props.initialPage.props.ziggy.url),
            };

            global.route = (name, params, absolute, config = Ziggy) =>
                route(name, params, absolute, config);

            return <App {...props} />;
        },
        progress: {
            color: "#4B5563",
        },
    });
});

<?php

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Inertia\Middleware;
use Tighten\Ziggy\Ziggy;

class HandleInertiaRequests extends Middleware
{
    /**
     * The root template that is loaded on the first page visit.
     *
     * @var string
     */
    protected $rootView = 'app';

    /**
     * Determine the current asset version.
     */
    public function version(Request $request): ?string
    {
        return parent::version($request);
    }

    /**
     * Define the props that are shared by default.
     *
     * @return array<string, mixed>
     */
    public function share(Request $request): array
    {
        $ziggy = new Ziggy($group = null, $request->url());

        return array_merge(parent::share($request), [
            // Add in Ziggy routes for SSR
            'ziggy' => $ziggy->toArray(),
            'auth' => [
                'user' => $request->user(),
            ],
        ]);
    }
}
