Webpack HookWebpackError: Missed semicolon

Hi, I’m having an issue when deploying to Netlify although my project works locally. I’m getting the following error in the deploy log.

HookWebpackError: /opt/build/repo/static/css/fa690d66ba98e8d7d95b.css:3:2231: Missed semicolon
7:20:56 PM: > Build error occurred
7:20:56 PM: Error: > Build failed because of webpack errors

This only happens when I have my dynamic route file in Next.js project [slug].js.
I’ve checked the file over for missing semi-colons but unfortunately to my knowledge, there aren’t any and my linter in VS code should pick up on adding and removing unnecessary semi-colons.
Is there a way to deploy without this check or config I can adjust to go around this behavior? I’ve added my file code down below along with the deploy log.
Thanks in advance for your help!
