I am running Joint-genotyping workflow on Terra. The ImportGVCFs task was performed in parallel with shards. However, not all the shards were run successfully. I got the error message for the Google cloud permission (see attached pic). Since it should be the same sample set (gvcfs) across all the shards, I don't understand why certain shards encountered the permission issue while some did not. I have previously run the same sample set with the same workflow and did not encounter this issue with permission.
Not sure what is the issue here and how to solve it.
