I'm working on a Nuxt 4 project and sometimes, after I update a file, J got the following error in the browser console:

Uncaught (in promise) SyntaxError: Identifier 'validate' has already been declared (at virtual:nuxt:/home/nicolas/Desktop/projets-web/wimefront/.nuxt/middleware.mjs:2:1)

Inspecting the generated .nuxt/middleware.mjs, I can see this:

 import validate from "/_nuxt/@fs/home/nicolas/Desktop/projets-web/wimefront/node_modules/nuxt/dist/pages/runtime/validate.js?v=3712f6c6";
    import validate from "/_nuxt/@fs/home/nicolas/Desktop/projets-web/wimefront/node_modules/nuxt/dist/pages/runtime/validate.js?v=3712f6c6"; // duplicated
    import manifest_45route_45rule from "/_nuxt/@fs/home/nicolas/Desktop/projets-web/wimefront/node_modules/nuxt/dist/app/middleware/manifest-route-rule.js?v=3712f6c6";

export const globalMiddleware = [
  validate,
  validate,
  manifest_45route_45rule
];

export const namedMiddleware = {
  auth: () => import("/_nuxt/middleware/auth.js")
};

I do not have any validate.js or validate.ts in my middleware/ or pages/ folder. I only have one custom middleware file, and it doesn't export or declare anything named validate.

I’ve tried:

rm -rf .nuxt node_modules + fresh npm install

Confirming I have no duplicate files named validate

Still, Nuxt seems to import the same internal validate.js file twice and crashes.

Almost every time I change something in a vue file, I need to do npm dev again (after npm dev I don't have the error)

Any clue?
