Reproduction

Describe the bug

If app.baseURL is configured, rendering an error page during SSR will fail with a message like this:

Cannot find any route matching /__nuxt_error?url=/&statusCode=404&statusMessage=Cannot+find+any+route+matching+/.&message=Cannot+find+any+route+matching+/.&stack&data.

I'll try to submit a PR for this shortly.

Additional context

It looks like this might have been introduced in nuxt/framework#8469:

https://github.com/nuxt/framework/blob/4311ce79f631a2599b233ead94642bf8cfc6f46e/packages/nuxt/src/core/runtime/nitro/error.ts#L51

With localFetch being used instead of $fetch, the baseURL option set here is no longer used.
