I just created new DE. While checking the third challenge in Reports and Dashboard Superbadge I get the following 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: TDOUZQDI

Hello,

I'm having trouble checking the challenge, I've checked other discussions and I've done exactly what others have done to pass but everytime I click check challange it gives me this error message:

Looks like something went wrong, please try again later.

I've logged out of both Developer Edition and Trailhead acc, used another new Developer Edition to redo the challenge and it gives me the same message.
