I'm not sure about that, because the default script behavior is to do
nothing. My understanding is that if there's a transaction, then TM

involved like that.

I agree with this; that's how I always do it: add logs at many places
and eventually find the exact line of code that leads to the error
(and _then_ figure out why).
