Check Challenge not working on API Basics Module - SELIQWNT

I was working on a module on Trailhead - Use REST API (API Basics ) and finished the challenge with workbench. However,  the 'Check Challenge' does not work with the following error: 

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: SELIQWNT


Can anybody let me know how to get this fixed so that I can continue with the module ? Thanks in advance.

Just to close the loop... Kevin's record did not have the correct description and were in fact null.

Is name space or domain in enable in your org ? If yes then you need to create developer org to complete your challenge

Please check below post for trailhead FAQ

I think my work is correct, but the challenge verification is still giving me an error.
If you think you've completed the challenge correctly, but you are still getting errors, make sure that you are using a fresh Developer Edition that does not have a namespace prefix. (What is a namespace prefix?) If you are still having trouble, use the “Share Feedback” button in the footer or on the right column to send a support request.
