error deploying react project with font-awesome import

[Ashkenazzio]

Hi, I'm trying to npm run deploy on my project where I'm storing the minified font-awesome css file and I'm getting the following error:

Creating an optimized production build...
Failed to compile.

./src/assets/css/font-awesome.all.min.css
ParserError: Syntax Error at line: 1, column 30

Of course the app works fine on development.
The error shows whether I'm importing the css to the main css file or the main js file...
This is a react project and I'm using npm. I only found some related old posts with potential solutions for a next.js project and yarn. Any suggestions?
