• I’m using the latest release

Describe the bug?

With the workflow below, I’m able to successfully run it on V32 and below of this action, but V33 and V34 are failing when I have a single file in the files to check list.

To Reproduce

jobs:
  sync:
    name: Check for config changes
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        id: checkout-code
        uses: actions/checkout@v3
        with:
          fetch-depth: 2
      - name: Get changed files
        id: changed-files
        uses: tj-actions/changed-files@v34
        with:
          files: |
            server/src/configs/default.json
      - name: Setup Node.js environment
        if: steps.changed-files.outputs.any_changed == 'true'
        uses: actions/setup-node@v3
        with:
          node-version: 16
          cache: 'yarn'
      - name: Run script
        if: steps.changed-files.outputs.any_changed == 'true'
        run: |
          yarn config-check
      - name: Commit and push changes
        if: steps.changed-files.outputs.any_changed == 'true'
        uses: devops-infra/action-commit-push@v0.9.0
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          commit_message: Sync character count for config ref file

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-20.04

Expected behavior?

I’m expecting it to not fail and report if the single file has changed.
