• Nuxt version: 4.2.0

Problem

When accessing an unregistered route or triggering a Nuxt error that renders the error.vue page,
the server-side Nuxt plugins are executed twice.

This behavior noticeably slows down page rendering because my server-side plugin performs some time-consuming asynchronous operations.

How can I make sure that my server-side plugin or handler executes only once per request to avoid performance issues, even when error.vue is rendered?

Code

File: app/plugins/demo.server.ts

export default defineNuxtPlugin(async () => {
  await new Promise((resolve) => setTimeout(resolve, 1000));
  console.log("demo.server.ts executed");
});
