Hey @markap14, I just tested it and I'm seeing a slightly different error (stacktrace below). It came about by following the same steps (generateFF -> replay event(s) -> let it sit a bit -> attempt to start generateFF). This time though it spews the error only a few times (3) and then properly creates FlowFiles. Let me know if there is any other information you need.
