Hi Nethravathi,

I would suggest you log out of all the accounts and log in again and also clear your browser cookies and history. check the challenge.
Another solution would try it in a different browser.

I hope it will be helpful.

Hi Rahul,
         Thank you for the reply,
    I tried both the possibilities which you have mentioned above
1. If I execute after deleting history and log in again I got the same error.
2. There is no namespace or domain enabled or created in my org. But after using fresh developer Edition it worked fine.
Just wondering why the same process did not work in my previous org.
