Error Message:
Challenge Not yet complete... here's what's wrong: 
The AccountTab Visualforce page does not include one or both of the following: the apex:slds tag in the page, or the slds-table value in the table.

Hello all. I am working on the new superbadge and getting stuck on Challenge 3 . I have tried several solutions but cannot get the data to display in table format. Here is my code below, my main issue is where to place the table class in realtion to the pageBlockTable.

<apex:page standardStylesheets="false" standardController="Account" recordSetVar="accounts" tabStyle="account" applyBodyTag="false">
    <apex:slds >
        
        <div class="slds-scope">
             
                <apex:pageBlock>
                    
                    <table class="slds-table"> 
                    <apex:pageBlockTable  value="{!accounts}" var="a">
                       
                        <apex:column headerValue="{!$ObjectType.Account.Fields.Name.Label}">
                            <apex:outputLink value="{!URLFOR($Action.Account.View, a.id)}">{!a.name}</apex:outputLink>
                        </apex:column>
                        
                    </apex:pageBlockTable> 
                    </table>
                    
                </apex:pageBlock>
            
        </div>
    </apex:slds>    
</apex:page>

 

I'm receiving the following error on challenge #6 of the Lightning Superbadge:

Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Delete failed. First exception on row 0 with id 0035000002hUBgRAAW; first error: DELETE_FAILED, Your attempt to delete Sam the ninja could not be completed because it is associated with the following adventure packages.: null, null : []

Looking at the Developer Console, it looks like the code which checks the system is forgetting to delete the Adventure Package records before deleting the Contact. Has anyone else run into this issue?

Thank you!
