I'm following this tutorial: https://developers.cloudflare.com/pages/framework-guides/deploy-a-svelte-site/ And I've also tried the Qwik tutorial. I'm running the dev server using

npm run pages:dev

so using wrangler. In the case of Qwik, in the console I can see the message:

Your worker has access to the following bindings:
- D1 Databases:
  - DB: ...

But the context is not provided to the request handler. In the case of Svelte,

export async function post(context) {
  const env = context.platform.env // This is undefined
}

The [SvelteKit docs](https://kit.svelte.dev/docs/adapter-cloudflare) do say "platform.env is only available in the final build and not in dev mode." But I'm not sure how anyone is doing development without the bindings. Just build every time I want to test? Am I missing something? Anyone have any suggestions or workaround?
