Trailhead Community for External Identity
I setup my community for partners. And then when I check the challenge I get the "Could not find a Community named "Partners"." error message. Unsure of steps to get around this issue. 
All Answers
Please check if you have done
Complete the Initial Community Setup in the module and also make sure you copy paste the community name Partners from the challenge.As trailhead is particular about names and labels.
Hope this helps you!
If this helps you please mark it as solved.
Thanks and Regards

I went back earlier this weekend and found the that I had not created the Partners profile. I just used the Partner like default profiles. Once I created the Partners profile it worked. I just didn't back out here to update the ticket.
Thanks for you help
