Hello All
I''m struck on Step 2

Challenge Not yet complete... here's what's wrong:
Ensure that the methods in the chartHelper class run as the system.

here is the chartHelper class.
public with sharing class ChartHelper {

    @AuraEnabled
    public static List<chartData> GetInventory(){
        List<chartData> cht = new List<chartData>();
        //ToDo: Perform a calculation that aggregates active Products that have a positive Quantity_Remaining__c
        //  And return a list of chartData
        //  Where the name is the Product Family and the Qty is the sum of the Quantity_Remaining__c
         
         AggregateResult[] groupedResults = [SELECT Family, SUM(Quantity_Remaining__c) FROM Product2 
                                              WHERE Quantity_Remaining__c > 0 AND IsActive = true
                                              GROUP BY Family];
        for (AggregateResult ar : groupedResults)  {
            cht.add(new ChartData(String.ValueOf(ar.get('Family')), Integer.ValueOf(ar.get('expr0'))));
        }
         /**for (AggregateResult ar : [SELECT Family, SUM(Quantity_Remaining__c) FROM Product2 
                                    WHERE Quantity_Remaining__c>0
                                        AND IsActive = true
                                             GROUP BY Family])  {
            cht.add(new ChartData(String.ValueOf(ar.get('Family')), Integer.ValueOf(ar.get('expr0'))));
        }**/
        
        
        return cht;
    }

    public class ChartData {
        public String name {get;set;}
        public Decimal val {get;set;}

        public ChartData(String name, Decimal val){
            this.name = name;
            this.val = val;
        }
    }

}

Any help highly appreciated
