Not excluding .png

[sekyondaMeta]

Running the workflow below does not seem to exclude the .png file. I have tried differernt permutations and combinations of adding the regex but nothing seems to work. Any ideas would be greatly appreciated.

Workflow:
`name: link check on PR

on:
pull_request:
branches: [main]

jobs:
linkChecker:
runs-on: ubuntu-latest

steps:
  - uses: actions/checkout@v4
    with:
      fetch-depth: 1

  - name: Get Changed Files
    id: changed-files
    uses: tj-actions/changed-files@v41

  - name: Check for Skip Label
    id: skip-label
    uses: actions/github-script@v6
    with:
      script: |
        const labels = await github.rest.issues.listLabelsOnIssue({
          owner: context.repo.owner,
          repo: context.repo.repo,
          issue_number: context.issue.number
        });
        return labels.data.some(label => label.name === 'skip-link-check');
      
  - name: Check Links
    if: steps.skip-label.outputs.result == 'false'
    uses: lycheeverse/lychee-action@v1
    with:
      args: --exclude '\.(pdf|zip|png|jpg)$' --accept=200,403,429 --base . --verbose --no-progress ${{ steps.changed-files.outputs.all_changed_files }}
      token: ${{ secrets.CUSTOM_TOKEN }}
      fail: true
      
  - name: Skip Message
    if: steps.skip-label.outputs.result == 'true'
    run: echo "Link check was skipped due to the presence of the 'skip-link-check' label."
    
  - name: Suggestions
    if: failure()
    run: |
      echo -e "\nPlease review the links reported in the Check links step above."
      echo -e "If a link is valid but fails due to a CAPTCHA challenge, IP blocking, login requirements, etc., consider adding such links to .lycheeignore file to bypass future checks.\n"
      exit 1`

error message:
