Hi @szymonpk, I believe that’s an incorrect use of the path input, as you’ll also need to specify the same path when using the checkout action or set diff_relative: true in order to get changes relative to a specified directory.

See https://github.com/tj-actions/changed-files/blob/main/.github/workflows/test.yml#L43 and for more information.

Sorry but it does not show diffs in charts directory. When using path:

        uses: actions/checkout@v3

      - name: Get changed files
        id: changed-files
        uses: tj-actions/changed-files@v35.5.4
        with:
          dir_names: true
          dir_names_exclude_root: true
          dir_names_max_depth: 2
          diff_relative: true
          json: true
          path: charts

I do not want to put the repository in charts.

You can pass the charts folder as a filter instead. Checkout the Usage documentation for more information

@jackton1 you mean files? But it exits with error when there are no changes (:exploding_head:)

@szymonpk Can you provide more information on what exits?
