Problem description

Hi.
I'm using the Java client to handle some functionalities in my cluster.
With the ElasticsearchSlmClient, I can create a policy and run it.

But when I try to run
slmClient.getStats();
I have the following error :

java.lang.RuntimeException: co.elastic.clients.transport.TransportException: node: https://my-cluster-address:9243/, status: 200, [es/slm.get_stats] Failed to decode response
