I suspect you are abusing the callback mechanism to do something it was
not intended for.  Callbacks are supposed to supply information for the
error message context field, *and nothing else*.  You'll probably break
things if you go outside that charter.  Accordingly, I see no reason why
a callback should care why it was called.

What are you trying to accomplish, really?
