Hi we’re using flyctl 0.0.452 now, a few hours ago on flyctl 0.0.451 we had no problems.
The issue we’re running into is that we have two processes running from our app, a web process and a worker process, and one volume that is (was) mounted specifically to the web process, e.g.
[mounts] processes = ["web"] source="media" destination="/app/media"
With that config I got
Error not enough volumes named media (1) to run 2 processes on our most recent deploy. I read Fly Apps on machine prerelease and removed both processes and source from mounts and planned to use Fly Apps on machine prerelease processes steps but now I get
mounts:  Source can't be blank mounts: source volume "" does not exist
