    List<String> traceIds = decoder.parameters().get("trace-id");
    checkNotNull(traceIds, "Missing trace id in query string: %s", request.getUri());
    String traceId = traceIds.get(0);
    logger.debug("handleRequest(): traceComponent={}, traceId={}", traceComponent, traceId);

    CharSource charSource = getDetailCharSource(traceComponent, traceId);
    if (charSource == null) {
