Hi Anton,
THANK YOU VERY MUCH for such detailed feedback. Unfortunately de upgrade process is not supported in this beta release as we are missing some migrators for the DB schema (and we didn’t want to delay the release more).
So the problem here is that the Zone schema is missing the Server pool of the zone.
However, the method should return in if just before getting the followers in line 215, and not failing with a segfault. I’ll take a look at it
