I'm not sure if this is the appropriate venue, but the manual and the grading script are out of sync for the Chapter 2 review. The script expects work to be done in the Default and Example domains, but the manual directs work within the MyCorp domain (p83 in CL110-RHOSP16-en-1-20200914). I've attached a screenshot of a diff.
In addition, the MyCorp domain is deleted in a previous exercise clean-up script - the creation is implied, and not covered in the solution.
