Hi team, Thanks in advance I try to create a BulkProcessor like [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/5.6/java-rest-high-document-bulk.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/5.6/java-rest-high-document-bulk.html) with the high-level client in the version 5.6 but I get this compilation error at this point: ... RestHighLevelClient rHLClient ... BulkProcessor bulkProcessor = BulkProcessor.builder( **rHLClient::bulkAsync** , listener,threadPool).build(); "Client is not a functional interface" If there is a better way to use that, please advise. I've been blocked on it. Thanks J. ---

Not sure. It looks correct to me. May be share a sample project? At least on 6.2, I don't have this issue. Strange that there is a mention of `Client` which you don't have in your code. ---

Hi, Thanks David, I have to use 5.6 version. Do you know what kind of problem can produce this error? In my search I found this: > Can you share an example with the 5.6 version? Thanks in advance, J. ---
