Regarding the failed Verify / Check for formatting & lint errors (pull_request):
The issue is with npx prettier .gitignore command where .gitignore file is modified in the commit.

The github actions workflow https://github.com/rudderlabs/rudder-transformer/actions/runs/11385814974/workflow will have to be changed to only include js, ts files to pass this check.

Here are the changes to be done:

• Modify Run format Checks
• Add a stage before it to filter out ts,js files

     - name: Filter JS/TS Files
        run: |
          echo "${{ steps.files.outputs.added_modified }}" | tr ' ' '\n' | grep -E '\.(js|ts|jsx|tsx)$' > changed_files.txt
          if [ ! -s changed_files.txt ]; then
            echo "No JS/TS files to format or lint."
            exit 0
          fi

      - name: Run format Checks
        run: |
          npx prettier --write $(cat changed_files.txt)
      - run: git diff --exit-code
