Hello,
There is an issue with Drupal.t() function when `vite: true` is enable in libraries.
_locale_parse_js_file() function does'nt use manifest to find js file to parse.
I fixed this issue locally with an extra lib js without vite that declares the translation strings. Ideally, this function should be able to go through the manifest.
Thanks,

I don't know if it's your problem but Vite may uglify Drupal variable in your function, so you get a.t() in your uglified JS.
And Drupal.t() needs to remain Drupal.t() even uglified
