Research direction
Start by reproducing the NodesInfoResponse call and inspect PluginStats.java, following the deserialization path through ObjectBuilderDeserializer.java and DelegatingDeserializer.java. Done means the nodes().info() response no longer fails with MissingRequiredPropertyException for PluginStats.opensearchVersion.
