Adding this plugin will fail compiling with "EnvCaster is not a function"

I've installed and added this plugin like mentioned in the docs, but starting the compiling throws an exception (see below).

vite.config.ts:

import EnvCaster from '@niku/vite-env-caster'

export default defineConfig({
  envPrefix: 'XYZ_',
  plugins: [
    EnvCaster(), // calling without options should be fine, right?
    vue({/*...*/})
  ]
})

Error running npm run dev:

The CJS build of Vite's Node API is deprecated. See https://vitejs.dev/guide/troubleshooting.html#vite-cjs-node-api-deprecated for more details.

Environment (from package.json):

What can be the issue here?
