An effect returned for this action is still running.

[DispoKen]

Hi, I have watched the video regarding this specific error message, however I still have no idea how to fix this error. In our test, we seemed to have covered all the possible effects, but we still end up getting this message. Is there a way to find what remaining effects that are still needed to address? I notice the error message sometimes does give us a helpful effect to look at, but for our error message it doesn't give any real hints aside from checking for long living effects which is hard to find. Any advice in helping to debug this is greatly appreciated!

Looks like you might need to add .receive(environment.mainQueue) for the effect that runs in your .onAppear action.

case .onAppear: return Effect(value: SomeAction.foo) .receive(environment.mainQueue)

This error means that one of the effects returned from .onAppear hasn't completed. So if you've covered effects you expect to fire, there still may be a long-living effect that needs to be cancelled by sending another action, like .onDisappear. Can you share what the effects the reducer(s) that handle .onAppear look like for that case? That might help us troubleshoot.
