# E1001

A composable that needs the Nuxt instance (`useNuxtApp()`, `useRoute()`, `useFetch()`, …) ran outside a plugin, Nuxt hook, route middleware, or Vue `setup()`. The most common trigger is calling it inside an async callback (`setTimeout`, `.then()`, after an `await`) where the context has been lost.

## Resolution

Call the composable synchronously at the top of `setup()` / a plugin / middleware and reuse the captured result later. For server-side async work, wrap the call with `nuxtApp.runWithContext()`.
