Vite project with type: module cannot build

[isgj]

Hi, I've a vite vue3 project. It has "type": "module" so only ESM. I prerender some pages, nothing special, the guide you can find for vue3. On dev all works fine, but if I build for production it errors with

import { createI18n } from "vue-i18n/dist/vue-i18n.runtime.esm-bundler.js";
         ^^^^^^^^^^
SyntaxError: Named export 'createI18n' not found. The requested module 'vue-i18n/dist/vue-i18n.runtime.esm-bundler.js' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'vue-i18n/dist/vue-i18n.runtime.esm-bundler.js';
const { createI18n } = pkg;

    at ModuleJob._instantiate (node:internal/modules/esm/module_job:123:21)
    at async ModuleJob.run (node:internal/modules/esm/module_job:189:5)
    at async Promise.all (index 0)
    at async ESMLoader.import (node:internal/modules/esm/loader:533:24)
    at async file:///media/isgjevori/data/git/fast-me/prerender.js:11:24

the import on the first line is on the entry-server.js the output of vite build --ssr src/entry-server.ts --outDir dist/server.
Can someone help?
