github actions bot not creating any comments

[frankwuyue]

I am running this action at debug mode and the log seems like everything is ok. but the github actions bot doesn't appear to comment on my pr. I am using a forked repo and created a pr to the forked repo, is that the problem? I think github actions' permissions are set to max privileges.

Event is push

Same story for me on a regular private repo.

Using these steps as a workaround:

      # region workaround for madrapps/jacoco-report
      # from https://github.com/marketplace/actions/delete-pr-review-comments
      - uses: aki77/delete-pr-comments-action@v1
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          bodyContains: |-
            [Coverage(%)]

      # from https://github.com/mshick/add-pr-comment
      - uses: mshick/add-pr-comment@v2
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}

Notice the message "prNumber: undefined" in the debug output. The PR is unknown because the workflow was triggered by a push. Change the workflow trigger to "pull_request" instead and it will work.
