src/runtime/server/api.ts imports createError from h3, which is not a dependency of @nuxt/icon, so it resolves to whatever h3 the package manager hoists. In a Nuxt 5 app where something else pulls in h3 v1 (pnpm, node_modules/.pnpm/node_modules/h3 -> h3@1.15.11), two things happen:

• h3 v1 is bundled into the server output next to Nitro's h3 v2, just for createError.
• The handler returns an h3 v1 H3Error, which h3 v2 does not recognise as an HTTPError. It is wrapped as an unhandled error: the status survives, but the message becomes "HTTPError", the body has unhandled: true, and every request logs a stack trace.

Minimal check with h3 2.0.8:

app.get('/v1', () => createErrorV1({ status: 400, message: 'Invalid icon request' }))
// 400 {"status":400,"unhandled":true,"message":"HTTPError"}
app.get('/v2', () => createErrorV2({ status: 400, message: 'Invalid icon request' }))
// 400 {"status":400,"message":"Invalid icon request"}

This exports createError from the existing #nuxt-icon-server-runtime virtual module (nitro/h3 on Nitro v3, h3 on Nitro v2), next to defineCachedHandler, so the handler always uses the server's own h3. The H3Event import stays type-only.

The repo's playground can't reproduce it because here h3 resolves to v2 at the root. Verified with eslint, vue-tsc --noEmit, the unit tests (apart from customize.test.ts, which needs a Playwright browser and fails the same way on main), and the playgrounds/nuxt5 build + test.

Walkthrough

The virtual server-runtime module now exports createError from nitro/h3 for Nitro v3 and from h3 otherwise. The shim declares the export. The server API imports createError from the virtual module. Its handler logic is unchanged.

Estimated code review effort: 2 (Simple) | ~5 minutes

Merge Risk: Minimal · up to 46c75

The change makes the icon API create errors with the server's own h3, which avoids the unhandled-error response seen with a hoisted h3 v1. No concrete merge-blocking risk remains. A mixed-h3 regression test would be a useful but optional follow-up.

Add a regression test for the mixed-h3 layout.

The Nuxt 5 playground test checks successful responses only. It does not exercise the error path or the h3 v1/v2 layout described in the PR. (raw.githubusercontent.com) Add a fixture with both versions and assert the error status, message and absence of unhandled.
