I made a nextjs project on my local windows machine which I can build with npm run build without any problem, but

when I try to build on my production server: Ubuntu 22.04.3 LTS with npm run build I get the following error:

./src/pages/about.tsx:7:20
Type error: Cannot find module '@/components/Layout' or its corresponding type declarations.

the code snippet from the component looks as:

import TestimonialPage from "@/components/about/TestimonialPage"
import Layout from "@/components/Layout"                    
import BaseButton from "@/components/base/BaseButton"

which is just a normal import statement.

I tried to change in my tsconfig.json the line with "moduleResolution": "bundler" with "moduleResolution": "node" but without any effect.

Also tried to change the "paths":

"paths": {
            "@/*": ["./src/*"]
        }

to

"paths": {
      "@/*": ["src/*"]
    }

but without success.

What else can I do?
