@IAmGav Here is a gist that contains the ./launcher rebuild app output - link
The only indication of ERROR is in the following group of lines (see below).
They seem to be related to database and role creation. Is there any way to bypass these actions? (which I think you would want to do during an upgrade since you working with a pre-existing instance)
Lines 88-95
