    // Assert traces and baggage are propagated correctly to server
    HttpRequest[] httpRequests = mockServerClient.retrieveRecordedRequests(null);
    assertEquals(1, httpRequests.length);
    String traceData = httpRequests[0].getFirstHeader("uber-trace-id");

    Response resp = target.request(MediaType.APPLICATION_JSON_TYPE).get();
    String responseStr = resp.readEntity(String.class);
    CallTreeNode callTree = mapper.readValue(responseStr, CallTreeNode.class);
    String strContext = span.context().contextAsString();
