If you're using a new DE and seeing this error, please post to the developer forums and reference error id: YZQQKILD

Hello guys, Im doing the second step of Superbadge App Customization Specialist, but when I try to check if its ok, it gives me the next error:


Challenge Not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: YZQQKILD

It is a new Trailhead Playground, which is the issue?

Thank you

Those are fulfilled:

Prework and Notes
- Grab a pen and paper. You may want to jot down notes as you read the requirements.
- Create a new Trailhead Playground for this superbadge. Using this org for any other reason might create problems when validating challenges.
- Install the unmanaged package to implement Volunteer Tracker assets for all users. If you have trouble installing a managed or unmanaged package or app from AppExchange, follow the steps in this article.
- Some of the terminology used in this superbadge is descriptive and may not match the name as it appears in the UI. This is to test your knowledge of Salesforce features and to find the correct one to satisfy a business need.

Hi,

Make sure you have formula field for "IsShiftVolunteer" instead of checkbox.Refer below linlk for similar issue.

It is a formula field returning a checkboxing, I've been trying with: $User.Id == Volunteer__c and with $User.Id == Volunteer__r.Id but no luck. 

Same issue.
