I can confirm this is happening to me as well, by the way. For instance, I can define the following just fine:

if: startsWith(github.ref, 'ref')

However, this errors out:

if: startsWith(github.event.head_commit.message, 'build')

Here's some of the output when run with -v:

DEBU[0000] Evaluating 'Boolean(startsWith(github['event']['head_commit']['message'], 'build'))' instead of 'Boolean(startsWith(github.event.head_commit.message, 'build'))' 

Thank you for act, by the way -- it's a great tool!

I want to follow up that a different thread provided a workaround (thanks @brunowego for linking!). The issue here is that act runs off an empty event JSON, so you've got to provide your own if you want to access that data. You can see a working example (plus the rest of the conversation that led to it), here.

Here's what I ran to allow for testing if on a commit message:

act -W components.yaml -s GITHUB_TOKEN=$GITHUB_TOKEN  -e <(cat << EOF
{
    "head_commit": {
      "message": "build latest"
    }
  }
EOF
)

This is how I'm working around the missing field, but since act populates the github.sha, surely it can also populate the head_commit field. Right?
