        It looks like the #{importers_class_names.join(', ')} importers implements its own way to import the repository.
        That means that the lfs object download must be handled for each of them. You can use 'LfsImportService' and
        'LfsDownloadService' to implement it. After that, add the importer name to the list of allowed importers in this spec.
