Hi,
I ran a modified method 3-Joint-Discovery from workspace help-gatk/Germline-SNPs-Indels-GATK4-hg38. The GVCF input files failed to import. Because it's a trial account, I couldn't modify the IAM settings of the data bucket. I've searched on storage.objects.list error topics, and found the ACL setting tricks but I'm not sure which part I should modify in the workflow.
