I encountered the same issue and the issue for me was a missing await on a database call that returned a promise in one of my assertions,

so by the time the response was returned the global transaction in the test suite had already been rolled back

Once I added the await, the error was resolved, so I suggest you double check any async calls in your tests which you may not be awaiting a response for.
