Hello,

I am trying to get details from \_nodes api using Elasticsearch java client 7.17.3.  
Following code block throws an exception. Is there anyone have an idea about what is wrong here?

Thanks,

```java
NodesInfoRequest.Builder nodesInfoRequest = new NodesInfoRequest.Builder();
NodesInfoResponse nodesInfoResponse = esClient.nodes().info(nodesInfoRequest.build());

```

```auto

This is a bug, and I opened [`NodeInfoPath.repo` should be optional · Issue #305 · elastic/elasticsearch-java · GitHub](https://github.com/elastic/elasticsearch-java/issues/305) so that we can fix it. Please subscribe to that issue to be updated when it's resolved.

In the meantime, you can use the the workaround described at [MissingRequiredPropertyException in a response | Elasticsearch Java API Client [8.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/missing-required-property.html)

Thanks having reported this issue!
