Hi Kevin,

Sorry for this issue you are facing.

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.

If the problem continues,  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.

Hope this helps.

Kindly mark this as solved if the reply was helpful so that it gets removed from the unanswered queue which results in helping others who are encountering a similar issue.

Thanks,
Nagendra

Thanks for following up Nagendra, 

Still having an issues.  In the dev org Namespace is not enabled.  I've done this exercise at least 10 times.  I've tried Chrome, Firefox, IE, Cleared Cache, went Incongito, keep getting the same error.   I've also created new playgrounds with no other exercises on them, to no avail.  The error is below.  (again)

Any other suggestions?

Hi Kevin,

Check there will be a step missing or something went wrong.
Basically, Salesforce will show a weird error if there is something wrong. 
This is not great news I did create many org for due to this Error.



Note: - Always use new playground Org for every new Module.



The same problem facing by many people and you can find a solution from here:-
