Hi,

I am facing below error while trying to verify Step 8-
Error: Please ensure that product2Extension and its methods are still working as specified in the earlier challenge.

Code below:
public class Product2Extension {

I'm facing the same issue.  By chance did you find a solution?
Amer AdminAmer Admin
I had to remove the filter logic from the save method in product2extension. For some reason the test they run for challenge 8 is totally different from the test they run for earlier challenges.
SR02SR02
@amer admin did you resolve the issue. I am also facing the same issue. can you help
kathir Apexkathir Apex

@Amer Admin ,

Could you please clarify me that which filter logic I need to remove
Amer AdminAmer Admin
Hi @SR02 @Kathir Apex  I change the following lines
                if(!String.isBlank(eachPW.productRecord.Name) && !String.isBlank(eachPW.productRecord.Family) && 
                   eachPW.productRecord.Family!=Constants.SELECT_ONE && eachPW.productRecord.isActive &&
                   eachPW.pricebookEntryRecord.UnitPrice!=null && eachPW.productRecord.Initial_Inventory__c!=null && 
                   eachPW.productRecord.Initial_Inventory__c!=0 && eachPW.pricebookEntryRecord.UnitPrice!=0) {
                       filteredProductWrappers.add(eachPW);
                   }   

to just this
                       filteredProductWrappers.add(eachPW);

My ProductWrapper should be supposed to be like below,

public ProductWrapper() {
productRecord = new Product2(Initial_Inventory__c =0, Name='Test Product', isActive=true); pricebookEntryRecord = new PricebookEntry(Unitprice=0.0);
}



Challenge completed!

I am also facing this issue. And when checked in debug logs for insert on some objects, getting error as Insufficient Privilege. Any idea which profile does Trailhead Bot uses and do we have to give accesses to any objects for this profile.
