Fields on Knowledge Article Not Displayed On Lightning Component

I have a Lightning component to display a list of Knowledge Articles. The code runs ok and seems to enter the `<aura:iteration` as the colons are displayed and looking at the debug log the query is returning results however the fields themselves like Title are not displayed when I run this in developer console.

component
   
<aura:component description="ArticleList" implements="forceCommunity:availableForAllPageTypes"  controller="ArticleListController">
  
    <aura:attribute name="articles" type="SObject[]"/>
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />

    <aura:iteration var="article" items="{!v.articles}">
        <p>{!article.Id} : {!article.Title} : {!article.ArticleType}</p>
    </aura:iteration>

    </aura:component>

controller
  
({

    doInit: function(component, event){
        var action = component.get("c.getArticles");
        action.setCallback(this, function(response){
        component.set("v.articles", response.getReturnValue());

        });
     $A.enqueueAction(action);
    }

})
  
apex controller
  
public with sharing class ArticleListController {

    @AuraEnabled
    public static List<List<SObject>> getArticles() {
        String searchVar = 'Unpredictable';
        List<List<SObject>> articles = [FIND :searchVar RETURNING      KnowledgeArticleVersion
        (Id, Title, ArticleType WHERE PublishStatus='online' AND Language = 'en_US' AND ArticleType IN ('Knowledge__kav','Attachment__kav'))];
        return articles;

    }

 }

Was missing something obvious was returning a list of lists, have to process it into a single list and it works.

Hi guys, is there any way we can show the related KB article attachment on community by retrieving related details via Lightning component.

For this, I am currently using the <ui:outputURL label="Attachment" value="{!v.articleDetail.Id}"/>  and here I am able to get the article id under the label "Attacment" but from here, I am not able to identify how to get the attachment open/ download in community.
