Hello There,

I am getting following error message for the trailhead module challenge "Extend Reports with Dashboards and Apps- https://trailhead.salesforce.com/trails/sales_admin/modules/sales_admin_sales_reports_for_lex/units/sales_admin_sales_reports_unit_3"

Error message-
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: PNJVBDNZ

Can anyone please help me with this?

Hi Kavitha,

Sorry for this issue you are encountering.

May I request you please confirm if you are using a brand new developer org for validating the challenge?

If you are using a brand new developer org then please double check that your org doesn't have a namespace enabled.If that doesn't help please give a try by restarting the batch

Still, if the problem persists log out of all accounts and log in once again in a different browser by clearing the cache and cookies which should probably do the trick.

Please let us know if this helps.

Mark this as solved if my reply was helpful.

Hello Nagendra,

Thank you for the detailed steps.

The Org I am using is a newly setup dev Org and the namespace prefix is not enabled for the same. Additionally, as you suggested I have cleared the browser cache. But, an error message is still observed on the trailhead.

I have tried for Chrome and Firefox browsers. 

Please let me know the possible solution to resolve the same.

Thank you,
