Published URL File APP.CSS

I am crossing an analysis on a website and while fuzzing and testing I came across the below URL: https//www.****.**.*/content/css/app.css Which generated the below output: /* Minification failed. Returning unminified contents. (856,107): run-time error CSS1036: Expected expression, found '}' (1838,90): run-time error CSS1019: Unexpected token, found '.'

The app.css should be accessible knowing that content and css directories are forbidden from server side. The Question I am searching an answer for: Does App.Css pose any security threat or issue from information disclosure perspective or can it be considered a vulnerability while published or is it a normal behavior ?
