I have created a Lightning component with following codes

Component Code

<aura:component controller="stDocus" implements="flexipage:availableForRecordHome,force:hasRecordId" access="global" >

    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    <aura:dependency resource="markup://force:editRecord" type="EVENT" />
    <aura:handler event="force:refreshView" action="{!c.doInit}" />
    <aura:dependency resource="markup://force:showToast" type="EVENT" />
    <aura:handler event="force:showToast" action="{!c.doInit}" />

    <aura:attribute name="recordId" type="string" />
    <aura:attribute name="docObj" type="List" />

    <div style="margin:30px auto; text-align:center; width:100%">
        <aura:iteration var="sld" items="{!v.docObj}">
            <div style="float:left; width:18%; margin:1%;">
                <img width="100%" id="theImage1" src="https://cdn1.iconfinder.com/data/icons/metro-ui-dock-icon-set--icons-by-dakirby/512/PowerPoint_alt.png"/>
                <a href="{! '/servlet/servlet.FileDownload?file='+sld.Id}" target="_blank" id="theLink1">{!sld.Name}</a>


Controller code

    doInit : function(component, event, helper) {
        var recordId = component.get("v.recordId");
        var action = component.get("c.getdocs");
            recordId: recordId
        action.setCallback(this, function(response){
            var state = response.getState();
            if (state === "SUCCESS") {
                var doc = response.getReturnValue();
                component.set("v.docObj", doc);

Apex Controller code

public  class stDocus
    //public String currentRecordId {get;set;}
    public Opportunity Oppo{get;set;}

 public List<Document> getdocs(String recordId)
        Oppo = [SELECT Id, Name, StageName, Amount FROM Opportunity WHERE Id = :recordId];
        List<Document> doc = [SELECT Id, Name, FolderId, Folder.Name FROM Document WHERE Folder.Name like :Oppo.StageName];
        return doc;

When I drag the custom Lightning component from the left side to the desired section of the Opportunity Record Page using Lightning App Builder, I get the following error as popup.

Unfortunately, there was a problem. Please try again. If the problem continues, get in touch with your administrator with the error ID shown here and any other related details. Unable to parse JSON response

I didn't get any error code. But when I inspected the console, I got the following log messages

Error in Surface: Unable to parse JSON response components/flexipageEditor/surface.js:5 Error in Surface: This page has an error. You might just need to refresh it. Action failed: flexipageEditor:component$controller$generate [$A.util.aa.ib(...) is not a function] Failing descriptor: {flexipageEditor:component$controller$generate}

Could you please help me find the issue and fix it?? I am stuck..

I have modified my code as per @Itai Shmida's suggestions in the comments. Now I am getting new errors.

Please help.

  • I would start by checking if recordId is empty in your doinit and if it is then exit. When you add to the layout in the app builder it runs the component to give you a preview. Since there will be no record Id your query in the class will throw an error and possibly an internal error. So give that a try and see if it helps. Or in your class check if null and return null. – Eric Mar 17 '17 at 13:51

    You should add to your markup: <aura:attribute name="recordId" type="String" />. also - I cannot see an attribute named docObj in your markup - according to your controller, you should add it also. – Itai Shmida Mar 19 '17 at 6:58
  • @ItaiShmida: I have added those attributes (updated the code in question. Please see). Still the same error. – AeJey Mar 20 '17 at 5:24

    In your sever side function you are returning a list of documents and in your client side - the attribute is one document – Itai Shmida Mar 20 '17 at 5:26

You need to add the


annotation to the method in your controller

public static List<Document> getdocs(String recordId)
        Oppo = [SELECT Id, Name, StageName, Amount FROM Opportunity WHERE Id = :recordId];
        List<Document> doc = [SELECT Id, Name, FolderId, Folder.Name FROM Document WHERE Folder.Name like :Oppo.StageName];
        return doc;

  • When I did that, I am getting another error - "Non static AuraEnabled methods may not have parameters" – AeJey Mar 20 '17 at 6:46
  • Fixed it @AeJey – Eric Mar 20 '17 at 6:46
