Log Context

Log”cannot read metadata for snapshot [{}]” classname is BlobStoreRepository.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 metaData = readSnapshotMetaData(snapshotId; snapshot.version(); indices; true);
            } else {
                metaData = readSnapshotMetaData(snapshotId; null; indices; true);
            }
        } catch (IOException | SnapshotException ex) {
            logger.warn("cannot read metadata for snapshot [{}]"; ex; snapshotId);
        }
        try {
            // Delete snapshot file first so we wouldn't end up with partially deleted snapshot that looks OK
            if (snapshot != null) {
                snapshotFormat(snapshot.version()).delete(snapshotsBlobContainer; snapshotId.getSnapshot());
