[REQUIRED] Environment info

firebase-tools: 13.11.4

Platform: macOS

[REQUIRED] Test case

https://github.com/JamieCurnow/firebase-web-framework-nuxt-loadNuxtConfig

[REQUIRED] Steps to reproduce

This is a fresh nuxt install that was created using npx nuxi@latest init

Open the repo.
Run npm i to install deps.
Run firebase init --debug
Choose only Hosting: Configure files for Firebase Hosting and (optionally) set up GitHub Action deploys.
Use and existing project or create a new one.

[REQUIRED] Expected behavior

Firebase init sets up the firebase project for the repo.

[REQUIRED] Actual behavior

The command fails due to a recent(ish) update in nuxt/kit.

Research

It looks like firebase-tools is calling loadNuxtConfig(dir) here and passing in dir as a string.
In a recent Nuxt update that was made in PR here loadNuxtConfig now requires an object to be passed in.

Quick Fix

Downgrade nuxt to v3.11.2 - npm i [email protected], and explicitly install @nuxt/kit at 3.11.2 - npm i -D @nuxt/[email protected].
Run firebase init and it should work.

Actual fix

Pass an object through to loadNuxtConfig() - it seems as though passing the dir through has no affect at least in firebase init.

async function getConfig(dir) {
  const { loadNuxtConfig } = await (0, utils_1.relativeRequire)(dir, "@nuxt/kit")
  return await loadNuxtConfig({})
}

I'll test a deploy and put up a PR.
