Error: Cannot read property 'name' of null

Seeing this failure when I close a pull request

Run xt0rted/pull-request-comment-branch@v1
  with:
    repo_token: ***

Workflow looks similar to this:

name: Slash Command Dispatch
on:
  issue_comment:
    types: [created]
jobs:
  slashCommandDispatch:
    runs-on: ubuntu-latest
    if: ${{ github.actor != 'dependabot[bot]' }}
    steps:

Adding a github.event.issue.state == 'open' is a workaround until this is handled properly, which it should be since it's an uncaught exception.

I resorted to use this https://github.com/xt0rted/pull-request-comment-branch/pull/202 PR instead
