Hello, I am gettign this error.

Step not yet complete in My Trailhead Playground 1
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: HXPPAYBX

This is when I try to complete this challege:

Create Reports and Dashboards for Sales and Marketing Managers

and earn this badge for Visualize your Data

Please help. 

Note: the Challenge is not working for both of my Orgs. I am launching it from the default my trailhead playground.
