If I swapped modules to topics, can (and should) I remove the following line from my config?

saveAs: { filename -> filename.equals('versions.yml') ? null : filename },

Remove it all

How do I need to declare this to adhere to the new syntax:

withName: 'SORT_CALLED_CHUNKS' {
        ext.args   = { '--output-type z --write-index=tbi' }
        publishDir = [
            mode: params.publish_dir_mode,
            path: { "${params.outdir}/variant_calling/" },
            saveAs: { params.varlociraptor_chunk_size > 1 ? null : "varlociraptor/${meta.id}/${it}" }
        ]
    }

Try : saveAs: { file -> params.varlociraptor_chunk_size > 1 ? null : "varlociraptor/${meta.id}/${file}" }

somehow my vscode still complains but lets see
