Resource interpreted as Stylesheet but transferred with MIME type text/plain

Every time Vuejs starts, I get it.

Resource interpreted as Stylesheet but transferred with MIME type text/plain: "https://unpkg.com/vue-croppa/dist/vue-croppa.min.css".

On the screen I get this I don't have crop its a file uploader.

When the form is submitted I receive a white page and I lose feedback on what I sent to the api.
