java.lang.IllegalAccessError: when accessing GraphQL API from vertx

[ooxaam]

I have a graphlQL client in Hasura (running on docker instance), which I want to access from vertex.

As per given example, following is my code:

@Override
    public void start(Future<Void> fut) {

        WebClient client = WebClient.create(vertx);

        JsonObject request = new JsonObject().put("query", "query { user { username } }");

        client.post(8080, "http://192.168.99.100","/v1/graphql")
            .putHeader("content-type", "application/json")
            .putHeader("x-hasura-admin-secret","somekey")
            .expect(ResponsePredicate.SC_OK)
            .expect(ResponsePredicate.JSON)
            .as(BodyCodec.jsonObject()).
                sendJsonObject(request, ar -> {
                    if (ar.succeeded()) {
                        JsonObject response = ar.result().body();
                        System.out.println("response = " + response.encodePrettily());
                    } else {
                        ar.cause().printStackTrace();
                    }
                });
    }

But I'm getting following exception:

Sounds like incompatible versions of Vert.x Web and Vert.x core are on the classpath. Let's continue the conversation on SO
