How can I get feedback when the js method does not exist?

[ApesTalk]

When i use WKWebViewJavascriptBridge call js method from iOS like this:

[self.bridge callHandler:@"notExistJsMethod" data:nil responseCallback:^(id responseData) {
        //can not get any response here
 }];

If sometimes the js method does not exist, i can not get any callback to know there is something wrong. If I can get feedback, I can do some default processing.

Search "console.log("WebViewJavascriptBridge: WARNING: no handler for message from ObjC:", message);" inside WebViewJavascriptBridge_JS.m and modify JS code like this:

 if (!handler) {
      console.log("WebViewJavascriptBridge: WARNING: no handler for message from ObjC:", message);
      if (message.callbackId) {
           var callbackResponseId = message.callbackId;
           _doSend({ handlerName:"", responseId:callbackResponseId, responseData:{"error": "jsHandlerNotFound"} });
      }                  
 }

This change require you provide a responseCallback or you cannot receive error callback
