Review comment:
Since you are throwing the exception, would it be better not to log the
error message twice? If you log the exception and then throw it, there’s a
chance that the exception will be logged again further up the call stack,
resulting in two log events for the same error. I would add eventId into the
errerMessage would be a good idea.
