args: -d ${{ env.GITHUB_WORKSPACE }}/cmd/bootstrap/ -w ${{ env.GITHUB_WORKSPACE }} build:linux

You can't expand env vars in an input. Should be fine to use -d ./cmd/bootstrap/ -w ./ build:linux

Interesting, I saw the logs didn't include it, but when running the action locally with act it expanded it (see screenshot in first post).

That said, I did try with:

      - name: Mage Build Linux
        if: matrix.os == 'ubuntu-latest'
        uses: magefile/mage-action@v1
        with:
          version: latest
          args: -d ./cmd/bootstrap/ -w . build:linux
          workdir: ${{ env.GITHUB_WORKSPACE }}

And got the same error:

@audiolion Do you have a link to your repo pls?

[audiolion]

It is a private repo, I can work on a reproducible example perhaps?

[crazy-max]

@audiolion Yes thanks I need some code base to be able to reproduce.

[audiolion]

ok so the issue is the local tool I was using to test my action, act, was failing, but when running this on github proper it works. My bad for bothering you about this! The repro I made fails locally and passes on github proper https://github.com/audiolion/mage-action-repro
