Command used with act

act

Describe issue

There is a discrepency between running 'act' and 'github' actions, specifically when using 'needs'.
When using 'act', it requires that I have 'runs-on', and fails if I don't.
Example:

call-refresh-workflow-passing-data:
    runs-on: ubuntu-latest
    needs: another-job
    if: ${{ needs.compare.outputs.all_modified_files != 0 }}
    uses: ...
    with: ...

When using the actual github actions, I need to remove 'runs-on', otherwise I get an error like below.
Example:

call-refresh-workflow-passing-data:
    needs: another-job
    if: ${{ needs.compare.outputs.all_modified_files != 0 }}
    uses: ...
    with: ...

The error I get when I add 'runs-on' line like the first example: Unexpected value 'uses'... Unexpected value 'with'

Act currently does ~~nice~~ not support reusable workflows.

@KnisterPeter Can you elaborate on this? Why does act require runs-on, but github does not?

I'm also confused. act does run the reusable workflow, but you have to add the runs-on property.

What are the options then? Manually remove the runs-on when it's time to deploy the action to my repository?

As I've said before, reusable workflows are not implemented.
With runs-on it does start to run the job as a regular job and that did not have uses or with keywords.

Why does act require runs-on, but github does not?

Because GitHub is developing faster than us. Before reusable workflows, there was no option to not have runs-on.
