# E5001

Code that relies on the app manifest ran while `experimental.appManifest` is disabled. The manifest powers features such as route rules matching and prerendered-payload detection on the client, so it must be enabled for them to work.

## Resolution

Enable the app manifest in your `nuxt.config`:

```ts
export default defineNuxtConfig({
  experimental: {
    appManifest: true,
  },
})
```
