private Buffer computeResponseBody(Message message) throws NoTypeConversionAvailableException {
    Object body = message.getBody();
    Exception exception = message.getExchange().getException();

    if (exception != null) {
        // we failed due an exception so print it as plain text
        StringWriter sw = new StringWriter();
        PrintWriter pw = new PrintWriter(sw);
        exception.printStackTrace(pw);

        // the body should then be the stacktrace
        body = sw.toString().getBytes(StandardCharsets.UTF_8);
        // force content type to be text/plain as that is what the stacktrace is
        message.setHeader(Exchange.CONTENT_TYPE, "text/plain");

        // and mark the exception as failure handled, as we handled it by returning
        // it as the response
        ExchangeHelper.setFailureHandled(message.getExchange());
    }

    return body != null
        ? Buffer.buffer(message.getExchange().getContext().getTypeConverter().mandatoryConvertTo(byte[].class, body))
        : null;
