Experienced programmer writer her first Elixir, and maybe bit off more than she can chew?
I’m trying to start two GenServers, where the second registers a subscription to the subscription to the first. Except the GenServer.call() call crashes out with “the process is not alive or there’s no process currently associated with the given name, possibly because its application isn’t started”
Full OTP/SASL logging seems to indicate it’s started, so I’m not sure what’s up? I guess the process names are wrong, but these are singleton servers using their module atoms as the name.
Full code is alchemical-swarm/hivemind
