Not sure why it’s happening… I only have one task, inside of a service.

It sounds like there is some other place in your code where you call .then() on a task instance but don’t catch() and it’s getting canceled as part of the test teardown. My hunch is that ember-concurrency is doing the right thing here, but perhaps the error message could be better, and could give you a little more information about the name of the task that’s failing.
