revenue cloud unable to be connected with trailhead

I create a revenue cloud test org from the link below, select the role as developer.   Trailhead | Promo Org Signup  and then connect this org from link below  Create Product Categories and Manage Attributes Effectively  but when I finished the challenge, then try to check the result, error occurred as below:  "We can’t find the Revenue Cloud org with our sample data. Make sure you select the special Developer Edition org with Revenue Cloud from the Hands-on Challenge picklist."
