[Bug]: Update theme workflow failed after Hugo v0.112

[aster-hu]

What happened?

The update-theme workflow indicates a panic error panic: runtime error: index out of range [0] with length 0. It seems like an issue caused by Hugo's latest release v0.112.1.

As a workaround, changing the Hugo version back to v0.111.3 solved the issue for me:

            - name: Setup Hugo
              uses: peaceiris/actions-hugo@v2
              with:
                  hugo-version: 0.111.3
                  extended: true

Could you please look into this to prevent future issue? My workflow file is the same as update-theme.yml in hugo-theme-stack-starter

Many thanks.

I guess this has to be related to Hugo 0.112.x’s CLI refactoring. I’m afraid the only solution is to stay in the old version until this gets fixed.

Thanks for the workaround!

This seems to be fixed already (I tested on 0.115.2).
