Throw real error messages on all failed attempts to get StateTransition
schedule (#15284)
# Objective Make it clear to the user why their program is failing rather than having an unhelpful `called Option::unwrap() on a None value` message. ## Solution Change the `unwrap()` calls to `expect()` calls, mirroring previously implemented error messages. ## Testing I have not tested these changes, but they are fairly trivial so I do not necessarily feel they need it.
