Grails 3.2.4 grails- spring -websocket 2.3 Error

=== UPDATE === (see original post below)

Although the error correction initiated by zyro has brought some improvements, the error still has not completely disappeared. It still looks like this:

Thus, only the second part of the error actually disappeared ...

=== ORIGINAL MAIL ===

In my Tomcat 8.0.28 catalina.out logs, I find a lot that follow erros. I assume this is caused by the websocket plugin that I used. I executed an implementation in a service class, for example:

def publishNewChart(def productId) {
        def linechart = chartService.getLinechart(Product.load(productId));

        brokerMessagingTemplate.convertAndSend("/topic/trade_chart/" + productId, linechart);
    }

And on the client side the following:

$(function() {
        var socket = new SockJS("${createLink(uri: '/stomp')}");
        var client = Stomp.over(socket);

        client.connect({}, function() {

            client.subscribe("/topic/trade_chart/${product?.id}", function(message) {
                var messageJson = $.parseJSON(message.body);
                refreshPriceChart($.parseJSON(messageJson.data));
                brushed();     
            });
        });
    });

Does anyone have a clue where the errors come from and how to deal with them?

Thank you for registering!
