Describe the bug

As part of our nuxt 2 to nuxt 3 migration we ran across an error where useNuxtApp is not defined in our build, while it works fine in dev.

To reproduce:

1. Clone the reproduction repo
2. npm i
3. npm run build
4. npm start
5. open localhost:3000 in your browser and open the javascript console

You should see the error useNuxtApp is not defined.

Logs

No response

Clone the linked tresorone/tresor-repro repository and follow the reported npm install, npm run build, and npm start steps. Inspect the production build behavior around the Nuxt Bridge configuration and compare it with development, then verify that opening localhost:3000 no longer reports “useNuxtApp is not defined” in the browser console.
