Please try with this snapshot (PR) - please try both with and without throwing the exception and check that you get the APM transaction displayed in the UI you expect in each situation (assuming there is a transaction here, if not please tell me that is not a relevant aspect). Thanks

Great, I'll update the agent and update the topic soon.

Thanks
