Cloudflare wrangler dev bug

A minimal repro case for wrangler dev causing HTTP 403 errors when fetching from the worker rendered web application.

Can be "fixed" by running wrangler in local mode.

Steps to repro

  1. Install deps
  2. Run with pnpm dev (Runs in non-local mode on Cloudflare's network)
  3. Load the in a browser application @ http://localhost:8787
  4. Observe stringified HTTP 403 error due to the fetch call
  5. With the terminal still open, turn on local mode with l
  6. After the application rebuilds, reload the browser window
  7. Observe the app rendering the response handled by the worker as expected
