Thanks for looking into this for me. I ended up totally re-installing everything manually (or not really manually but using Homebrew) and that seemed to work much better. Something about MAMP must have been causing all kinds of problems.

No worries - at least there is a workaround for now!

I see the issue, I went to search and created the advanced query there instead of going to Maniphest and creating it in there.

Hmm, I don't have that option in mine. Is the problem that my query doesn't yet return any results? I'm mostly trying to set this stuff up for later.

Sorry for dragging this on further, but I actually tried these steps before opening the task and I didn't see a way to select my existing query. Where in this UI should my query be appearing?
