get-rocks-modified-and-build-scan-test-publish.yaml fails in empty repos

[DnPlas]

Bug Description

There seems to be an issue with the get-rocks-modified-and-build-scan-test-publish.yaml workflow. If the repository is empty (does not contain any rockcraft project), the workflow will return the following error:

# Run dorny/paths-filter@v2
  with:
    token: ***
    list-files: none
    initial-fetch-depth: 100
Error: Input required and not supplied: filters

This is caused because we are not passing any filters to the paths-filter action used in the workflow.

      - uses: dorny/paths-filter@v2
        id: filter
        with:
          filters: ${{ needs.get-all-rock-paths.outputs.paths}}

To Reproduce

Run the workflow in a repository that does not contain any rockcraft project

Environment

Same as the CI - the environment is actually set by the offending workflow

Relevant Log Output

Run dorny/paths-filter@v2
  with:
    token: ***
    list-files: none
    initial-fetch-depth: 100
Error: Input required and not supplied: filters
