Action on workflow_run: prevent from running on push event

Body

Hi. I have a on: workflow_run Action that runs upon completion of one of more other Actions and posts a comment in a pull request. It only makes sense for the workflow_run Action to run when the dependent Actions were run due to a pull request (even though the latter could also run on a push). I am looking for a way to restrict that action so it does not run on a push.

The yml looks as follows:

name: add artifact links to pr
on:
  workflow_run:
    workflows: ["Build LaTeX document", "Build LaTeX diff document"]
    types: [completed]

jobs:
  artifacts-url-comments:
    name: add artifact links to pull request and related issues job
    runs-on: [ubuntu-latest]
    if: github.event_name != 'push'
    steps:
      - name: add artifact links to pull request and related issues step
        uses: veitbjarsch/artifacts-url-comments@main
        env:
            GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
            prefix: "Status:"
            format: "name"
            addTo: "pull"

I thought the line if: github.event_name != 'push' would do it, but the workflow runs anyways (and fails because... it's not a pull request). I tried moving the if just after the uses:, but that fails in the same way.

What is the correct way to corral such a workflow?

Thank you in advance!

Upvote, I have similar scenario, but could not find any solution so far.

test.yml:

name: Test

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

deploy.yml:

name: Deploy

on:
  workflow_run:
    workflows: [ 'Test' ]
    types: [ completed ]
    branches: [ main ]

Deploy action is now ran when I open a pull request for merging into main, but that should not happen. The Deploy workflow_run should only be executed if a push to the main branch happened in the Test action that triggered this workflow.

I suggest to read the workflow_run webhook documentation (I only looked this up, not tested)

if: github.event.event != 'push'

Sources: https://docs.github.com/en/webhooks/webhook-events-and-payloads#workflow_run and https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/accessing-contextual-information-about-workflow-runs#github-context

github.event_name is always workflow_run in your example

Even with a if you get entries for workflow runs, but no Action Minutes.
