vite build ends up with "[intlify] Not found '...' key in '...' locale messages."

Setting up vite with vite-plugin-vue-i18n according to the documentation followed by
`npm run dev` and navigating to `localhost:` Will always display "message" and the console tells me

```
[intlify] Not found 'message' key in 'ja' locale messages.
[intlify] Fall back to translate 'message' key with 'en' locale.
[intlify] Not found 'message' key in 'en' locale messages.
```
Both in a "full-scale" application and the minimal example below.

### Expected behavior

Localized message string.
