Ubuntu – Getting push event added file name in GitHub actions

I need to read file zip file name in GitHub actions. But in following code, both Artifact and Artifact1 are returning blank values. What is wrong with the code?

name: SCR Initial

on:
  push:
    branches:
      - main
    paths:
      - 'test/**zip'

jobs:
  SCR:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Artifact zip name
        run: |
          echo "Commit text = ${{ github.event.head_commit.message }}"
          echo "Artifact name= ${{ github.event.head_commit.added }}"
          echo "Artifact1 name = ${{ github.event.head_commit.added[0] }}"

I have checked in workflow logs and able to see blank.

    In a push event triggering a github actions workflow, the head_commit object payload doesn’t contain those message and added fields.

    This head_commit object is filled as follow (example from a personal repository):

    {
...
    "head_commit": {
      "author": {
        "email": "[email protected]",
        "name": "GuillaumeFalourd",
        "url": "https://api.github.com/users/GuillaumeFalourd"
      },
      "private": false,
      "pulls_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/pulls{/number}",
      "pushed_at": 1624727244,
      "releases_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/releases{/id}",
      "size": 230,
      "ssh_url": "[email protected]:GuillaumeFalourd/poc-github-actions.git",
      "stargazers": 2,
      "stargazers_count": 2,
      "stargazers_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/stargazers",
      "statuses_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/statuses/{sha}",
      "subscribers_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/subscribers",
      "subscription_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/subscription",
      "svn_url": "https://github.com/GuillaumeFalourd/poc-github-actions",
      "tags_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/tags",
      "teams_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/teams",
      "trees_url": "https://api.github.com/repos/GuillaumeFalourd/poc-github-actions/git/trees{/sha}",
      "updated_at": "2021-06-26T17:05:58Z",
      "url": "https://github.com/GuillaumeFalourd/poc-github-actions",
      "watchers": 2,
      "watchers_count": 2
    },
...
}

    Here is an example of a full push event JSON if you want to check its structure.

    To access the last push commit message for example, you would need to use ${{ github.event.commits.[0].message }}

    ${{ github.event.head_commit.added }} does not exist any more, see this blog post for more information.

    In addition to what GuiFalourd already said, you can do something like this:

    git diff --diff-filter=A --name-only HEAD~1

    This will list only the files that were added (=A) in the latest commit.
