error TS2339: Property 'nuxtIcon' does not exist on type 'AppConfig'

[frasza]

Recently upgraded Nuxt Icon in my SPA Nuxt app (using Nuxt 3.3 with SSR set to false and strict typescript) and hit a bug when running npm run generate.

This still seems to be an issue, except this time the errors are on properties of the nuxtIcon instead of the nuxtIcon object.

It can be reproduced with the repo linked in the original issue by upgrading the dependencies to latest versions:

"devDependencies": {
    "nuxt": "^3.5.0",
    "nuxt-icon": "^0.4.1"
  },
  "dependencies": {
    "typescript": "^5.0.4",
    "vue-tsc": "^1.6.5"
  }

I'm getting the same errors when building. However, they are not reported when using nuxt typecheck 😯

[mandragora-hub]

Errors still persist with updated packages.

In dev, it works as expected. The bugs emerge on a build step. This only occurs if you have typecheck in true
