Hello friends.  I just installed DREAMHOUSE App and I was trying to access any PROPERTY, when I got this message "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: 120013661-373515 (473429469)".   

I installed and unistalled Dreamhouse as part of the exercises of the Trailhead, not sure if this is the reason of the issue.  Thank you for any help !!

If the problem is still persistant, then I would try a new playground and a fresh install of the package.
