Hi,

We have a problem with the community public version. 

When a user public try to view the knoledge base, appear the next error: "ERROR: You don't have access to the Apex class named 'DataCategoryController'."

I find information about that but is referent to profiles acces to Apex Class. The error appear to public user so i can´t give acces to Apex Class if are public user without licences.

The Apex Class is a controller for a aura component. When i see the component with my salesforce user no appeat the error.

Code:

public class DataCategoryController {
    @AuraEnabled
    public static Wrapper getDataCategories(){
        
        Wrapper wrap = new wrapper();
        wrap.items = new List<Node>();
        wrap.label = 'Ayuda y soporte tecnico';
        
        Map<String, Knowledge__DataCategorySelection> mapKDCS = new Map<String, Knowledge__DataCategorySelection >();
        List<Knowledge__DataCategorySelection> lstkdcs =  [SELECT DataCategoryGroupName,DataCategoryName,Id FROM Knowledge__DataCategorySelection];
        
        for(Knowledge__DataCategorySelection KDCS :lstkdcs ){
            mapKDCS.put( KDCS.DataCategoryName, KDCS );
        }
        
        for(Knowledge__DataCategorySelection KDCS :mapKDCS.values() ){
            Node DCNode = new  Node();
            DCNode.label = KDCS.DataCategoryName;
            DCNode.name = KDCS.DataCategoryName;
            DCNode.expanded = true;
            wrap.items.add( DCNode );
        }
        
        system.debug('wrap: '+ wrap);
        return wrap;
    }
    
    @AuraEnabled
    public static List<Knowledge__kav>  getArticleVersion(String topicName){
        
        Set<Id> setTopicEntyId = new Set<Id>();
        
        List<TopicAssignment> lstTA = [SELECT EntityId FROM TopicAssignment WHERE Topic.Name = :topicName LIMIT 900 ];
        system.debug('lstTA: '+lstTA);
        
        for(TopicAssignment ta :lstTA){
            setTopicEntyId.add(ta.EntityId);
        }
        
        system.debug('setTopicEntyId: '+setTopicEntyId);
        
        List<Knowledge__kav > lstKAV = [
            SELECT Id, Title, FirstPublishedDate, LastPublishedDate,UrlName 
            FROM Knowledge__kav
            WHERE PublishStatus = 'Online' AND Id in  :setTopicEntyId];
        system.debug('lstKAV: '+lstKAV);
        return lstKAV;
    }
    
        
    public class Wrapper{
        @AuraEnabled
        public String label{get;set;}
        @AuraEnabled
        public List<Node> items{get;set;}
    }
    
    public class Node{
        @AuraEnabled
        public String label{get;set;}
        @AuraEnabled
        public String name{get;set;}
        @AuraEnabled
        public Boolean expanded{get;set;}
        @AuraEnabled
        public List<node> items{get;set;}
    }
}

Do you know the solution for this error?
Do you know another method to solve the error?

Thanks!
