 // org/lucee/cfml/lsp/LSPEndpoint.cfc
 component {

-        // Process LSP message and return response
-        return jsonMessageResponse;
+        var json=deserializeJSON(jsonMessage);
+        systemOutput(json,1,1);
+        json.addition="myAddition";
+        return serializeJSON(json);
     }
 }
