I was wondering if there is an official way to handle ajax errors in yii2. I can submit forms using ajax and if everything goes well in the action that handles the ajax call, I get a success response. However, when things don’t go according to plan (e.g. syntax error in the controller action), nothing happens on the sender view. So the question is: How do I configure the controller action to redirect the debug display from the controller and deal with it, for example by displaying it to the user in the view.
