Trying to use action on push.

Getting this error on push. I think it is because it is not grabbing the commit id. I changed ${{ github.event.pull_request.head.sha }} to ${{ github.sha }}. Is there anything else I should do or maybe this won't work on push?

I set up everything exactly according to the instructions as far as I can tell. I am using the phpcs.yml example given in my .github/workflow directory.
