I wonder if the library can provide a debugging mode that would provide a helpful default implementation of no_transition that could help identify the unknown transition rather than requiring the user to write something? Such a function might access internal details, perhaps only provided in the said debugging mode, that would be clearer about the source state and event for which no transition was provided than would user-level code.
