I am trying to use the afterRender event in a custom component (below is the component markup, js handler and the error I am seeing). I have taken out all the code in the handler but I still can't get around the error. I also don't know what parameter I should be setting for value in the component markup for the handler. The documentation around afterRender is pretty sparse so wanted to see if someone in the group could help. If I remove the afterRender handler, the component shows without error.
 
Thank you.
 
<!-- COMPONENT MARKUP -->
<aura:handler name="afterRender" action="{!c.afterRender}" value="{!this}"/>
 
//js controller afterRender
afterRender: function (component, helper) {
                       
        this.superAfterRender();           
       
    }
