I was working on "Lightning Experience Rollout Specialist" super badge challenges and stopped by an error when trying to complete the 8th challenge.
This is the 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: WZTUILTU

I tried it using new playgrounds and still not working. Not sure what's wrong. Any guidance would be greatly appreciated..!!
