Example usage of GetSourceRequest

Trying to use ElasticsearchClient to get the source of a document. No problem getting the document but when I use GetSourceRequest as below it results in an error during deserialization. I couldn't find any unit tests or examples. Any suggetions?

GetSourceRequest getRequest = new GetSourceRequest.Builder().index(indexName).id(id).build();
GetSourceResponse<ObjectNode> getResponse = elasticsearchClient.getSource(getRequest, ObjectNode.class);

Welcome!

What's the full stacktrace?

Java client version is 8.8.2

I should note that when I tried to get the document using GetRequest.Builder() everything was fine. Following was ok

GetRequest getRequest = new GetRequest.Builder().index(indexName).id(id).build();
GetResponse<ObjectNode> getResponse = elasticsearchClient.get(getRequest, ObjectNode.class);

I can reproduce this. Let me check a bit more what is happening.
