Code:

            GetSnapshotResponse snapshotRepositories = client
                    .snapshot()
                    .get(b -> b);

in the spec the Field GetSnapshotRequest.repository is mandatory.

[swallez]

Support for Azure repositories is indeed missing. It's an issue in the upstream API specification which is fixed in https://github.com/elastic/elasticsearch-specification/pull/1771

The fix will be included in the Java client 7.17.6 & 8.4.0.

That being said, client.snapshot().get() is used to retrieve snapshot information and has two required properties, repository and snapshot (which can be * or _all to retrieve all snapshots). To retrieve snapshot repository information, you should use client.snapshot().getRepository().
