@Meshari17 what is the reason behind the revert? Did you see that you can replicate the logic natively with the actions?

jobs:
  rebase:
    name: Rebase
    if: github.event.issue.pull_request != '' && contains(github.event.comment.body, '/rebase')

Workaround unitl new Actions support neutral strategy

See how it was before: https://developer.github.com/actions/creating-github-actions/accessing-the-runtime-environment/#exit-codes-and-statuses

NEUTRAL_EXIT_CODE=0

skip if no /rebase

echo "Checking if comment contains '/rebase' command..."
(jq -r ".comment.body" "$GITHUB_EVENT_PATH" | grep -Fq "/rebase") || exit $NEUTRAL_EXIT_CODE

skip if not a PR

echo "Checking if issue is a pull request..."
(jq -r ".issue.pull_request.url" "$GITHUB_EVENT_PATH") || exit $NEUTRAL_EXIT_CODE

if [[ "$(jq -r ".action" "$GITHUB_EVENT_PATH")" != "created" ]]; then
echo "This is not a new comment event!"
exit $NEUTRAL_EXIT_CODE
