Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): 2.15.0

Describe the issue:
I am unable to delete any snapshots from S3 backup repository.
Any snapshot I try to delete gives the same error:

curl -s -k -u admin:PASSWORD_GOES_HERE --cert ./admin.pem --key ./admin.key -XDELETE https://localhost:9200/_snapshot/OUR_BUCKET_NAME/full_snapshot-2024.05.07-21:45:01 | jq .

      }
    ],

  },
  "status": 500
}

Any idea how I fix this? Looks like snapshot full_snapshot-2024.01.19-11:45:01 is corrupt?
