Could not find pull request warning for pull_request closed event

[convers39]

Description:

I need to run a workflow after a PR is closed or merged. So I set the types as closed. Now the issue is since the PR is closed first in order to trigger the workflow, labeler seems not able to find a closed PR and gives me a warning message of Could not find pull request <number>, skipping. I have some tasks which rely on labeler, so wonder if there is any way to work with closed PRs.

on:
  pull_request:
    types: [ closed ]
jobs:
  delete_channel:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      id-token: write
    steps:
      - name: チェックアウト
        uses: actions/checkout@v4
        with:
          ref: ${{ github.event.pull_request.head.sha }}
      # ...
      - id: pr_labels
        uses: actions/labeler@v5

Action version:
Specify the action version

v5

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Self-hosted

Repro steps:

basically the action file I posted

Expected behavior:

Possible to deal with closed PRs.

Actual behavior:

Could not find pull request <number>, skipping warning, and the following steps are skipped.

currently, I tried another workflow that can retrieve the labels after PR is closed

Try adding the following to the params, I went through the code quickly and it seems prNumber is retrieved from a param pr-number.

pr-number: ${{ github.event.number }}
