          # You can opt for 'only-labels' instead if your usecase requires all labels
          # to be present in the issue/PR

Avoid stale for specific assignees:

name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3

        with:
          exempt-all-pr-assignees: true

Debugging

Logs:
To see the debug output from this action, you must set the secret ACTIONS_STEP_DEBUG to true in your repository.
There is a lot of logs so this can be very helpful!

Statistics:
If the logs are enabled, you can also enable the statistics log which will be visible at the end of the logs once all issues were processed.
This is very helpful to have a quick understanding of the whole stale workflow.
Set enable-statistics to true in your workflow configuration file.

Dry-run:
You can run this action in debug only mode (no actions will be taken on your issues and pull requests) by passing debug-only to true as an argument to the action.

More operations:
You can increase the maximum number of operations per run by passing operations-per-run to 1000 for example which will help you to handle more operations in a single stale workflow run.
If the debug-only option is enabled, this is very helpful because the workflow will (almost) never reach the GitHub API rate, and you will be able to deep-dive into the logs.

Job frequency:
You could change the cron job frequency in the stale workflow to run the stale workflow more often.
Usually this is not very helpful though.
