[SalesForce] You might just need to refresh it. Assertion Failed!: Provider type not supported : false Failing descriptor

Iam facing following error with my code:

This page has an error. You might just need to refresh it.
Assertion Failed!: Provider type not supported : false
Failing descriptor: {c:Picklistversion2}

can anyone take a look into this :

<aura:component controller="Picklistverion2" implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" >

 <aura:attribute name="set" type="object"/>

 <div class="slds-text-body_regular">
  <aura:iteration items="{!v.set}" var ="d">        
 <lightning:input  label="Profile"  value="{!d.Name}" onchange="{!c. doInit}"/> 
              </aura:iteration>       
         </div>
</aura:component>

Controller function for this :

doInit: function(component, event, helper) {
  //call apex class method
  var action = component.get('c.PermissionSetLst');
  action.setCallback(this, function(response) {
   //store state of response
   var state = response.getState();
   if (state === "SUCCESS") {
    //set response value in ListOfAccount attribute on component.
    component.set('v.set', response.getReturnValue());
   }
  });
  $A.enqueueAction(action);
 }

my Class for this

public class Picklistverion2 {
     @AuraEnabled
    public static List<PermissionSet> PermissionSetLst()
    {
         return [SELECT Name FROM PermissionSet WHERE IsCustom = TRUE AND IsOwnedByProfile = FALSE];
    }        

}

I want my query output inside my lightning input so that after i''ll move ahead for further conditions
