https://github.com/emmanuelchucks/cloudflare-vite-plugin-playwright-repro

Describe the Bug

To reproduce the bug I basically cloned https://github.com/cloudflare/playwright/tree/main/packages/playwright-cloudflare/examples/todomvc

It worked when I ran pnpm wranger dev

Then I installed the vite plugin and setup vite.config.ts. When I run pnpm vite dev and try to visit localhost:5173 I get "Cannot read properties of undefined (reading 'indexOf')"

Please provide any relevant error logs
