SyntaxError: /src/components/shared/logo/_Logo.css: Unexpected token (1:0) Mocha Css

I am having an odd error imo, I don't really understand why I am seeing this now as I've been using these tests without any problems, I left it for a month or so and tried to run again and saw the following:

Error

npm test

> wekindred.com@0.0.1 test /var/www
