Describe the bug

We are running OpenSearch of version 2.15.0 and backing up OpenSearch data to AWS S3.

When multiple snapshots exist in snapshot repo and delete one of the snapshot by API, it will return 400 with error groupSize must be greater than 0 but was -1, but the snapshot is successfully deleted.
When only one snapshot exist in snapshot repo, the snapshot deletion will succeed and return 200.
