Describe the Bug

Since I switched from v11 to v12 I can’t get my nextjs site deployed with github actions. I receive this weird error that I dont get with yarn dev or yarn start locally:

/home/runner/work/beumsk.github.io/beumsk.github.io/node_modules/next/dist/shared/lib/router/utils/sorted-routes.js:7

and my repo: https://github.com/beumsk/beumsk.github.io

I searched here and online without success. Can anyone help me or at least point me in the right direction?

Thank you so much already 😃

Expected Behavior

The production build should work as it does in my local env.

To Reproduce

I don’t know how I can make it possible to reproduce.

Yes, switching to Nextjs v12 needs a more recent version of Node, which you have to explicitly choose in your integrate.yml. Here is the way to specify it to node 14 for example, as you can read here: https://github.com/actions/setup-node

- uses: actions/setup-node@v3
        with:
          node-version: 14

Hope it fixes your issues as well!
