nuxt build && wrangler deploy

- Redirected configurations cannot include environments but the following have been found:
        - prod-eu
        - staging-us
        - staging-eu
  
  
      Such configurations are generated by tools, meaning that one of the tools
      your application is using is generating the incorrect configuration.
      Report this issue to the tool's author so that this can be fixed there.
    - You have specified the environment "staging-us", but are using a redirected configuration,
  produced by a build tool such as Vite.
      You need to set the environment in your build tool, rather than via Wrangler.
      For example, if you are using Vite, refer to these docs:
