Before

	node.on("input", function(msg) {
            node.client.publish(node.topic || msg.topic, msg.payload, msg.headers);
        });

After

            node.on("input", function(msg, send, done) {
                if (node.topic && msg.payload) {
                    try {
                        msg.payload = JSON.stringify(msg.payload);
                    } catch {
                        msg.payload = `${msg.payload}`;
                    }
                    node.serverConnection.publish(node.topic, msg.payload, msg.headers || {});
                    done();
                }
            });

Start with the STOMP node input handler shown in the issue and compare the pre-refactor publish call with the current JSON.stringify path. Reproduce the XML payload case, then verify that XML is published as XML while JSON payloads retain their expected behavior; the issue does not name a file or test to run.
