Super Linter Exclude not working on MD files on github actions workflow

Question

I am trying to exclude .md files from my super linter because it gets caught every time but can't seem to figure it out can someone help?

jobs: 
  super-linter:
    name: Lint code and merge
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Super-Linter
        uses: github/[email protected]
        with:   
          exclusions: |
            markdown: true
          files: ${{ join(github.event.push_request.changed_files, ',') }}

  deploy: 
      runs-on: self-hosted   
      needs: [super-linter] 
      steps: 
        #- uses: actions/checkout@v2  #this is used for if you want to push all source code into runner       
        - name: update code base 
          working-directory: /test_pipe/www/html 
          run: sudo git pull origin master        
        - name: restart   
          working-directory: /test_pipe/www/html
          run: sudo systemctl restart nginx  

I have tried using exclude and ignore but with no luck.

According to github/super-linter's Filter linted files section, you can use the environment variables to include and exclude files i.e. FILTER_REGEX_INCLUDE and FILTER_REGEX_EXCLUDE respectively.

See its Environment variables section for more details.

Apart from that, it provides VALIDATE_* variants of Boolean environment variables too to enable/disable linting per language so you can use VALIDATE_MARKDOWN: false and it should also work for your use case.

Not sure why you're using its with: exclusions or with: files inputs but https://github.com/github/super-linter/tree/v4.10.1 doesn't list anything like that.
