Hey guys, I started to using the new S3 Endpoint for sync our local backups.

The backup process went fine with one 800ish GB snapshot, but the GC gave me the following error in the task log:

Code:

2025-10-03T00:00:02-04:00: TASK ERROR: failed to list chunk in s3 object store: failed to parse response body: custom: missing field `StorageClass`

I'm using a Nearline class bucket.

Any thoughts on how to fix the GC?
