pnpm react-router dev fails after upgrade to 7.4.1

[mattymattdev]

I'm using React Router as a...

library

Reproduction

1. Upgrade to the 7.4.1 versions specified here https://github.com/remix-run/react-router-templates/tree/main/cloudflare
2. Run pnpm run dev

Specifically, vite.config.ts looks like this:

import { reactRouter } from "@react-router/dev/vite";
import { cloudflare } from "@cloudflare/vite-plugin";
import tailwindcss from "@tailwindcss/vite";
import { defineConfig } from "vite";
import tsconfigPaths from "vite-tsconfig-paths";

export default defineConfig({
  plugins: [
    cloudflare({ viteEnvironment: { name: "ssr" } }),
    tailwindcss(),
    reactRouter(),
    tsconfigPaths(),
  ],
});
