Got exception "Invalid receiver type interface org.apache.http.Header ...."

[Nossiac]

Since vertx.io does not provide any official elasticsearch wrapper, then I come to this lib. I'm currently testing 0.9.0-ec7.10.1 with vertx-4.1.1, JDK 1.8.

Here's my testing,

   void TestEs(Vertx vertx, VertxTestContext testContext) {
        RestClientBuilder builder = RestClient.builder(new HttpHost("xxxxxx",));
        RestHighLevelClient client = RestHighLevelClient.create(vertx, builder);

        GetAsyncSearchRequest var1 = new GetAsyncSearchRequest("event");
        RequestOptions var2 = RequestOptions.DEFAULT;
        client.asyncSearch().getAsync(var1, var2,  res -> {
            if (res.failed()) {
                testContext.failNow(res.cause());
            } else {
                System.out.println(res);
                testContext.completeNow();
            }
        });
    }

It gave me exceptions as below:

Did I make any mistake? Or it's indeed a compiler bug? any workaround solution?

@Nossiac Did you find any solution to this issue. I'm getting the same error with opensearch client version 1.2.4
