I have one error

Hai Guys.
When i doing the trailhead projects reports and dash boards.
i creating the dashboards following error is coming .
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: JDVMZQOC 

please tell me how to rectify the following error please

Hi Ashok, 

I did some digging on this one and here's what I found (thanks to Chris Duarte for the help):

It's difficult to predict all scenarios for all the challenges and organizations, so the recommendation is to create a new developer org and use that for recreating the dashboards and reports for your challenge.  You would keep your "trailhead" org in tact with all your badges and other rewards, but create a new DE org for working on the challenges explicity.  Chances are this should fix your issue, assuming you follow the challenge correctly.
