Closes #32912

📚 Description

Check if the getAppManifest() call returned a 404 or 403 (usually returned when the CDN does not have access to list files). If so, proceed anyway so that the app:manifest:update hook can still be called.

This issue affects both Nuxt 3 and 4.

Walkthrough

The code update modifies the handling of errors when fetching the application manifest in a Nuxt client plugin. The change introduces a try-catch block around the getAppManifest() call, specifically suppressing errors of type FetchError with status codes 404 or 403, while rethrowing other errors. The logic is updated to allow currentManifest to be undefined if the manifest is not available, and subsequent code uses optional chaining to safely access currentManifest.id. No changes are made to exported or public entities.

17-25: Make FetchError status check more robust across environments

ofetch’s FetchError may expose status via different properties (status, statusCode, or response?.status). To avoid brittle checks, derive the status via a fallback chain before comparing, and only swallow 403/404.

-    } catch (e) {
-      // The build is already outdated but the manifest is not cached
-      if (!(e instanceof FetchError && (e.status === 404 || e.status === 403))) {
-        throw e
-      }
-    }
+    } catch (e) {
+      // The build is already outdated but the manifest is not cached
+      if (e instanceof FetchError) {
+        const status = e.status ?? e.statusCode ?? e.response?.status
+        if (status === 404 || status === 403) {
+          // swallow
+        } else {
+          throw e
+        }
+      } else {
+        throw e
+      }
+    }

Optional: If you expect “offline”/network errors to occur during deployments, consider also swallowing status === 0 (network error) to preserve the update flow.

Learning: In `packages/nuxt/src/app/components/nuxt-root.vue`, when optimizing bundle size by conditionally importing components based on route metadata, prefer using inline conditional imports like:

```js
const IsolatedPage = route?.meta?.isolate ? defineAsyncComponent(() => import('#build/isolated-page.mjs')) : null
```

instead of wrapping the import in a computed property or importing the component unconditionally.

1-1: Importing FetchError is appropriate for precise error narrowing

Good call to import the runtime class for instanceof checks in the client.


30-30: Optional chaining here achieves the intended behaviour

Comparing against currentManifest?.id ensures app:manifest:update still fires when the current manifest isn’t available. This directly addresses the stale-build scenario.
