Hello, I have succeeded running the -r mutect2_once_more version of the pipeline, but then it failed at the level of

GATK4_GENOMICSDBIMPORT

process. This is the error :

java.lang.IllegalArgumentException: Null object is not allowed here.

The associated command.sh looks as follows, will a null value for the workspace path

#!/usr/bin/env bash -C -e -u -o pipefail
gatk --java-options "-Xmx29491M -XX:-UsePerfData" \
    GenomicsDBImport \
    --variant NTD15.vcf.gz  \
    --genomicsdb-workspace-path null \
    --intervals genome.bed \
    --tmp-dir . \

To my understanding this is caused by the following line https://github.com/nf-core/createpanelrefs/blob/671ff01bd003e4b2abf889d7534588275860cade/subworkflows/nf-core/bam_create_som_pon_gatk/main.nf#L49, where [] is passed instead of a valid parameter. Would it be possible to check this and provide a patch that I can test please? thanks in advance,
