Hi, 
I got the above error while trying to "Create an Indicator Badge Apex Service "
And the code of INDICATOR_Controller  shown as below 
public class INDICATOR_Controller {
    private static SObject sobj;
    @AuraEnabled
    public static String getSObjectLabel(String sObjName){
        String label = Schema.getGlobalDescribe().get(sObjName).getDescribe().getLabel();
        return label;
    }
    @AuraEnabled
    public static List<INDICATOR_Service.Indicator> getIndicators(String recId, String objectName){
        getSObject(recId, objectName);
        if(sobj != NULL){
            List<INDICATOR_Service.Indicator> indicators = INDICATOR_Service.getIndicatorBadgesForObject(sobj);
            return indicators;
        } else{
            return null;
        }
    }
    public static void getSObject(String recId, String objectName){
        List<String> fNames = INDICATOR_Service.getFieldsToQueryForObject(objectName);
        if(fNames.size() > 0){
            String query = 'SELECT Id,'+ String.join(fNames,',')+' FROM '+ objectName +' WHERE Id =\''+ recId +'\' LIMIT 1';
            List<SObject> results = Database.query(query);
            if(results.size() == 1){
                sobj = results[0];
            }
        }
    }
}

Please Help!

Thanks,

Hello developer heroes!

I'm working through the Apex modules on Trailhead and can't seem to get past this one: https://developer.salesforce.com/en/trailhead/force_com_programmatic_beginner/apex_triggers/apex_triggers_bulk.

Hopefully this doesn't read like a 'please complete the course for me' kinda post, but I have written a trigger that I believe meets the criteria but it isn't passing the check, so I wanted to seek the guidance of the experts.

The challenge is to do this:

Create an Apex trigger for Opportunity that adds a task to any opportunity set to 'Closed Won'.

To complete this challenge, you need to add a trigger for Opportunity. The trigger will add a task to any opportunity inserted or updated with the stage of 'Closed Won'. The task's subject must be 'Follow Up Test Task'.The Apex trigger must be called 'ClosedOpportunityTrigger'

- With 'ClosedOpportunityTrigger' active, if an opportunity is inserted or updated with a stage of 'Closed Won', it will have a task created with the subject 'Follow Up Test Task'.
- To associate the task with the opportunity, fill the 'WhatId' field with the opportunity ID.
- This challenge specifically tests 200 records in one operation.

And here is the trigger I have come up with, which compiles OK and stands up to a manual (though admittedly unbulkified) test:

trigger ClosedOpportunityTrigger on Opportunity (after insert, after update) {

    List<Task> taskList = new List<Task>();
    
    for (Opportunity opp : [SELECT Id, StageName FROM Opportunity WHERE StageName = 'Closed Won' AND Id IN :Trigger.new]){
                    
            taskList.add(new Task(Subject = 'Follow Up Test Task',
                                  WhatId = opp.Id));
       
    }

    if(taskList.size()>0){
        
        insert taskList;
        
    }
    
}

I have tried replacing the SOQL with a straightforward 'for (Opportunity opp : Trigger.new)' and having the taskList.add inside an IF that checks for Closed Won - no luck. I also thought about checking to see if the stage was being changed to Closed Won, rather than the trigger firing on every edit, but I don't think this is what the module is asking for.

Where do you think I'm going wrong?

Huge thanks in advance!
