I'm working in the Trailhead, "Omni-Channel for Lightning Experience".  Specifically I'm on "Understand Skills-Base Routing".

I have followed the directions, but there is an issue with this Trailhead.  In the section called "Set Up Skills-Based Routing", there are some steps.  Step #10 asks you to edit the Service Resource Layout.  And while my object does exist, the Layout was never created.

That's the first issue.  No problem.  I'll create the page layout; which I do, adding the fields Name, Resource Type, Active, and User.  I save the layout and assign it to my profile, System Administrator. 

In the next section, Create Service Resources for Agents, I launch the Service Resources object and click New.

I add myself (who is system admin), save the record and am immediately greeted with this error:

Unfortunately, there was a problem. Please try again. If the problem continues, get in touch with your administrator with the error ID shown here and any other related details. Error ID: 319840274-32622 (-324617948)

Previously, under a different trailhead playground, I tried to add a user who has the Custom: Support Profile, but kept getting an error saying the user wasn't a Chat user; but none of the instructions in the previous lessons for this particular Trailhead ever mention anything about assigning or making a non System Admin a Chat user....

Seems this section could use some clean up for those trying to follow along.  Luckily for this one trailhead, I don't have to pass anything except a quiz...but I haven't looked at what follows and whether it expects you to have completed what's described.

Have I missed something?
