Prerender fails setting `--env staging` since `dist/server/wrangler.json` is flat | TanStack | Page 1

I am trying to bun run build my application, which uses pre-rendering. When I run bun run dev (which sets CLOUDFLARE_ENV=local), everything works fine, but when I bun run build:staging (which sets CLOUDFLARE_ENV=staging), it fails at the prerender step when it fails to spin up a preview. I get this error:

▲ [WARNING] Processing dist/server/wrangler.json configuration:

    - No environment found in configuration with name "staging".
      Before using `--env=staging` there should be an equivalent environment section in the
  configuration.

      Consider adding an environment configuration section to the wrangler.json file:
      ```
      [env.staging]
      ```



error during build:

Any ideas on how I can get the preview server to run properly?
