I did a deploy, which says that it failed because of a validation error
in what looks like something to do with the UserApp. So I looked at the
"details", and this is the details?

What we need here is a pointer to what thing within Designer needs to be
fixed, not just its directory object name. Even better would be some
kind of indication as to what sort of problem it has that caused this
here validation error, so that I have some chance of fixing it.
