Hello
When Checking Challenge # 7, I get the following error.  I created this org yesterday brand new just for this superbadge.  The error says the following.
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: DTERBIZZ

I am 99% certain all of the steps are 100% as I got 1 error notice on report before rechecking and getting this error.  Please advise.
